Generally instances use:

person.is_appropriate_sex = person.is_opposite_sex

but some instances define it as:

person.is_appropriate_sex = not person.is_opposite_sex

It's an implementation detail, you shouldn't worry about it.

I wish you were taking the mickey, but I suspect you're not...

Got any more information? Googling doesn't come up with anything that

Followers of Shushla celebrate the new year at the time of the spring
equinox.

This has been the cause of  bloody wars between the Northern and

In principle, if you can access the device from a C program, you can do  
the same thing with Python and ctypes. Mismatched C runtimes (between  
Python and the library) might be an issue in some cases, like sharing a  
FILE struct or allocating memory from one side and freeing it on the other  
side. But "sane" APIs (for some definition of sanity) should be usable  
without problems.

The way you do this is to write a Windows hook.  The WH_CBT hook intercepts
WM_ACTIVATE and WM_DEACTIVATE calls system-wide.

However, that requires injecting the hook DLL into every process with a
Windows, and you certainly don't want to do that in Python.  Write a
minimal C DLL to be the hook, and have it send messages to your Python
process.

If you are ok shelling out to a binary:

I am trying to convert the pdf to a png, but without having to run external

The C runtime doesn't create objects.  Python does use it to allocate
memory, but in the Microsoft run-times, malloc and free call the Win32 heap
APIs, no matter what the version.

It's true that mallocing in one CRT DLL and freeing in another can cause
problems, but in Python, I don't think that can happen.  Proper Python
add-ins call Python APIs to create and destroy objects, so only the Python
runtime will manage the memory.

Not at all: if you inherit from any of the many pagan (that is, non-
Christian) religions that celebrated midwinter festivals, or the old 
Roman Saturnalia festival that Christianity itself inherited Christmas 
from, you shouldn't raise an exception.

Alternatively, you can delegate to any object that understands about 
holidays, parties, celebrations and gift-giving.

Subject changed: Bug in combining htmlentitydefs.py and ElementTree?

[André]

Sorry for the top posting - I found out that the problem I encountered
was not something new in Python 3.0.

Here's a test program:

import xml.etree.ElementTree
ElementTree = xml.etree.ElementTree
import htmlentitydefs
class XmlParser(ElementTree.ElementTree):
def __init__(self, file=None):
ElementTree.ElementTree.__init__(self)
parser = ElementTree.XMLTreeBuilder(
target=ElementTree.TreeBuilder(ElementTree.Element))
parser.entity = htmlentitydefs.entitydefs
self.parse(source=file, parser=parser)
return

f = open('test.html')
tree = XmlParser(f)
tree.write('test_out.html', encoding='utf-8')
==
This program should be run with the following test file (test.html):
=




test


Α


==
If run as such, it will print out the following:
--



test


Α


---
Notice how it is Α that appears instead of Α

This is the behaviour with both Python3.0 and 2.5.  (When I was
running with Python 2.5, I was always preprocessing the files with
BeautifulSoup, which removed many problems).

If I use "my_htmlentitiesdef.py" described in a previous message, I do
get an Alpha printed out (admittedly, not the character entity).

I would prefer to find a way to process such files and get Α
instead...  (or even, to process files with hard-coded characters e.g.
é instead of é and have them processed properly...).

unicode-challengedly-yrs,

André

[] Medical Imaging Systems
In recent years, extensive research has been performed to develop more
and more efficient and powerful medical imaging systems. Such systems
are crucial for medical specialists, allowing a deeper analysis and to
understand what is going inside the human body, and therefore they
play an essential role for adequate medical diagnosis and treatments.
To accomplish efficient and powerful medical imaging systems, many
research works have being done in many domains, like the ones related
with medical image devices, signal processing, image processing and
analysis, biomechanical simulation and data visualization.
The main goal of the Workshop "Medical Imaging Systems" is to bring
together researchers involved in the related domains, in order to set
the major lines of development for the near future.
Therefore, the proposed Workshop will consist of researchers
representing various fields related to Medical Devices, Signal
Processing, Computational Vision, Computer Graphics, Computational
Mechanics, Scientific Visualization, Mathematics and Medical Imaging.
The Workshop endeavors to contribute to obtain better solutions for
more efficient and powerful medical imaging systems, and attempts to
establish a bridge between clinicians and researchers from these
diverse fields.

The proposed Workshop will cover topics related with medical imaging
systems, such as:
* image acquisition
* signal processing
* image processing and analysis
* modelling and simulation
* computer aided diagnosis
* surgery, therapy, and treatment
* computational bioimaging and visualization * software development *
virtual reality * telemedicine systems and their applications

[] D-TV
Scope:
In contrast to traditional TV DTV is a telecommunication system for
broadcasting and receiving moving pictures and sound by means of
digital signals. It uses digitally compressed modulation data, which
requires decoding by a specially designed television set or a standard
receiver (set-top box) as well as via PC-TV based on ADLS (VDSL).
Digital Television has several advantages regarding technically as
well as content and programme related aspects. One of the most
significant is the use of a smaller channel bandwidth.
This frees up space for more digital channels, other non-television
services such as pay-multimedia services and the generation of new
revenue models based on interactive advertisement and marketing
features. Furthermore there are special services such as multicasting
(more than one programme on the same channel), electronic programme
guides and in

Jim:

I have a copy of Fedora 8 in a VMachine.  I found that I could get the 
Pydoc Server to start by doing the following.  I also found that I had 
to install tkinter first.  I then modified a copy of "pydoc" in usr/bin 
as follows:

#!/usr/bin env python2.5

import pydoc
if __name__ == '__main__':
 pydoc.gui()# Was pydoc.cli() in the original 
"pydoc"



I then named it "pydocgui", saved it to the desktop for now, then set it 
to open with Python in its document properties.

If I double click on this file, then select run from the dialog, the 
Pydoc Server opens.

Sorry, that was just cut-and-pasted from the browser (not the source);
in the source of the processed html page, it is
'Α':0x0391, # greek capital letter alpha, U+0391

i.e.  the "&" was transformed into "&" in a number of places (all
places above ascii 127 I believe).

You may well be right in that the problem may lie elsewhere.  But as

To understand that problem better, it would have been helpful to see
what line 401, column 11 of the input file actually says. AFAICT,
it must have been something like "&é;" which would be really puzzling
to have in an XML file (usually, people restrict themselves to ASCII
for entity names).

Sure, however, your first version ALSO has the Greek capital letter
alpha there; it is just spelled as Α (which *is* a valid spelling
for that latter in XML).

Thanks; I now think that htmlentitydefs is just as fine as it always
was - I don't see any problem here.

As stated above, I was using ElementTree to parse an html file and
sending the output to a browser.
Without an additional parser, I was getting the following error
message:

Traceback (most recent call last):
File "/Users/andre/CrunchySVN/branches/andre/src/http_serve.py",

  line 1157, in _default self._parser.ErrorColumnNumber)
xml.parsers.expat.ExpatError: undefined entity é: line 401, column 11

So, I tried to specify an additional parser via

if python_version >= 3:
import htmlentitydefs
class XmlFile(ElementTree.ElementTree):
def __init__(self, file=None):
ElementTree.ElementTree.__init__(self)
parser = ElementTree.XMLTreeBuilder(
target=ElementTree.TreeBuilder(ElementTree.Element))
ent = htmlentitydefs.entitydefs
for entity in ent:
if entity not in parser.entity:
parser.entity[entity] = ent[entity]
self.parse(source=file, parser=parser)
return

The output was "wrong".  For example, one of the test I used was to
process
a copy of the main dict of htmlentitydefs.py inside an html page.  A
few
of the characters came ok, but I got things like:

'Α':0x0391, # greek capital letter alpha, U+0391

When using my modified version, I got the following (which may not be
transmitted properly by email...)
'Α':0x0391, # greek capital letter alpha, U+0391

It does look like a Greek capital letter alpha here.

Alternatively, if the page is *not* gb-2312, you must first *decode*
it from its original encoding. Suppose the original encoding is
windows-1252, you do

  page = page.decode("windows-1252")
  page = page.encode("gb-2312")

Of course, for HTML, that may be tricky, as the file may include
an encoding declaration (XML declaration or http-equiv header). So if
you recode it, you might have to change such declarations as well.

I dunno. The file does specify its charset, so unless IE ignores that
and tries to guess and fails, it should work fine.

Big-endian binary data to/from Python ints?

[William McBrine]

Here are a couple of functions that I feel stupid for having written. 
They work, and they're pretty straightforward; it's just that I feel like 
I must be missing an easier way to do this...

def net_to_int(numstring):
"""Convert a big-endian binary number, in the form of a string of
arbitrary length, to a native int.
"""
num = 0
for i in numstring:
num *= 256
num += ord(i)
return num

def int_to_net(num):
"""Convert a native int to a four-byte big-endian number, in the form
of a string.
"""
numstring = ''
for i in xrange(4):
numstring = chr(num % 256) + numstring
num /= 256
return numstring

The situation: I'm getting a four-byte packet from a socket that consists 
of a big-endian 32-bit integer. (It specifies the length of the data that 
follows.) I have to send the same thing in reply. send() and recv() work 
with strings... I'm familiar with ntohl() and htonl(), but those expect/ 
return integers.

The above would not execute; seek needs at least one argument.
"Perform a seek()" was an abbreviated way of telling you to seek to
the position at which you want to write i.e. (current) end of file so
you would use seek(0, 2).

"Why": already explained; some stdio implementations require it.

I'm sorry, but your statement of the alleged problem doesn't make much
sense. Possibly you mean EOL (end of line), not EOF (end of file). In
any case, when opening a file in binary mode, lines (and end-of-line
conventions) are quite irrelevant -- you use a_string = f.read(nbytes)
to read (or f.write(a_string) to write) as many bytes as you think you
need, starting at the current position in the file.

Perhaps if you provided more precise information than "VisualBasic was
not happy", like: the exact code that you ran, and the exact [hint:
use the repr() function] contents of the two input files and the
output file, plus what you expected the contents of the output file to
be, plus whatever VB had to say about the output file, we might be
able to help you with the problem.

Cheers,
John

.read() returns the bytes exactly how it downloads them. It doesn't
interpret them. If those bytes are GB-2312-encoded text, that's what
they are. There's no need to reencode them. Just .write(page) (of
course, this way you don't verify that it's correct).

(BTW, don't use 'file' as a variable name. It's an alias of the 'open()'
function.)

Bug in htmlentitydefs.py with Python 3.0?

[André]

In trying to parse html files using ElementTree running under Python
3.0a1, and using htmlentitydefs.py to add "character entities" to the
parser, I found that I needed to create a customized version of
htmlentitydefs.py to make things work properly.

The change needed was to replace (at the bottom of the file)

for (name, codepoint) in name2codepoint.items():
codepoint2name[codepoint] = name
if codepoint <= 0xff:
entitydefs[name] = chr(codepoint)
else:
entitydefs[name] = '&#%d;' % codepoint

by

for (name, codepoint) in name2codepoint.items():
codepoint2name[codepoint] = name
entitydefs[name] = chr(codepoint)


It does work for me ... but I don't know enough about unicode to be
sure that it is a proper bug, and not a quirk due to the way I wrote
my app.  So, I thought it would be appropriate to post it here so that
unicode experts could determine if it was indeed a bug - and file a
bug report/write a patch.   The same code is present in Python 3.0a2 -
but I have not tested it under this new version.

You can pipe the pdf through ghostscript and read the png back from
ghostscript's stdout. Like:

gs -q -sDEVICE=png16m -sOutputFile=- - 

Use that command in subprocess with the  stdin/stdout as pipes, send
your PDF data to the process and read the PNG output back.

However you must be aware that this can deadlock if the output is large
enough. So putting the input or the output in a real file is probably safer

Almost full XSLT2 Support (minus XML Schema support, IMHO not too useful 
part of XSLT2) would be the best as writing templates in a general 
templating lang as XSLT is great if you use the same ones in cross-lang 
systems which are e.g. usable in Java or Python environment.

Especially XPath Support with temporary trees (and not just fragments) 
is very useful (I know EXSLT is an option, but still not quite as good 
as XSLT2). Or stuff like sequences in XPAth2 simplifies development 
quite a bit (I think the following is possible, have not used it in the 
last weeks though):
(a, b, c)[EMAIL PROTECTED]'123']

Or using sequences for ordering stuff like e.g.:

in XSLT1:



which in XSLT2 simply is:


I used the Python extension functions some years ago in Pyana and later 
in LXML which is great but these naturally very much depend on Python 
then...

I know XML and therefor also XSLT seem not the most favourite of tools 
in the Python community but for e.g. document based systems like CMS 
systems XML and XSLT is at least in my experience a great combination.

this:

myfile=open('test.txt','r+')
content = myfile.read()
myfile.seek()

myfile.close

I'm not upset, but if my wording seems to be like an upset person I'm
sorry, English is not my first language, and I'm very bad at choosing
words.

A simple solution (but possibly inefficient, if the object is complex
and need to be exchanged thousands of times) for the problem mentioned
is to convert the object to a common agreed format that both sides can
understand when transferring the data such as a simple string (not a
string object, just simple string with no strings attached: pun (not)
intended).

In your case, which is:
> Assume an application embedding Python being compiled with MSVC 8.0.
> It uses the runtime msvcr80.dll.  If you now pass objects created in
> your application to the Python interpreter which is compiled with MSVC

No, you're not asking for trouble, you're passing the object to the
Python DLL, not to the msvcr71 behind the Python so it shouldn't be a
problem in a good designed program and DLL. This isn't a case about
msvcr71 talking with msvcr8, nor it is msvcr71 with your program, nor
it is msvcr8 with Python DLL, this is a case of Your Program talking
to Python DLL.

One way to solve this is:
Assuming you don't have access to Python internals (although since
Python is open source, you do have access) you could build a wrapper
around Python Interpreter. The wrapper has two functions. One: accepts
a string input (string as simple string, not string object) that
describes the original object and returns a file that Python can pick
with pickle. Two: accepts a pickled object and returns a string that
describes the pickled object that Your Application could understand.

This functions could be built in into Your Application, but the
easiest way is to build the wrapper with Python, as you won't need to
know how to read and write pickled file.

For a simple case, where the object that needs to be passed is
predetermined your function could just pass any data that is required
to reconstruct the original object to the wrapper (for example, in a
vector class, just the values of x, y, z), a versatile way to pass
them is by command-line arguments, like "wrapper 1 2 3 > output". The
wrapper would add any other required infos (methods, operator
overloads, etc) before pickling the object and call the Python DLL to
unpickle the object. For the vice versa case, the wrapper unpickle the
file returned from Python DLL, and convert it to a format Your Program
could understand, then notifying your program.

Of course there may be other easier, more efficient ways to solve this
problem, but this is a proof-of-concept that it is possible to compile
your application in VS8 while still using the official VS
Python.

But I can't think of a need why Python DLL needs to be used like this
though

The answers boil down to:
- use the templating engine that comes with your web framework
or
- use whatever templating engine you like
or
- just do it by hand

The remaining work is obviously such a no-brainer that there's no need 
for a specific package, and so application specific that there's 
probably nothing like a one-size-fits-all answer. IOW : you're not 
likely to find more "helpful" answer - and your above comment won't 
help. FWIW, I just wrote a function generating an html table from a list 
of header and a list of rows. I wrote the most Q&D, straightforward, 
braindead way, it's 17 lines long, doesn't even need an import 
statement, and took me less than 2 minutes to write - that is, far less 
work than reading your post and answering it.

Hi,

In the programs I write and package, I usually distribute msvcp71.dll
and MSVCR71.dll. I include them in the directory that the Python exe
I've created is running from. However, it sounds like you are running
pure code, not something packaged with py2exe.

You might run sfc and see if your dlls are ok. See 
http://support.microsoft.com/kb/310747

A friend of mine swears by this: http://wiki.djlizard.net/Dial-a-fix

Of course, it might be as simple as just uninstalling and reinstalling
Python.

Re: CPython and a C extension using Boehm GC

[MrJean1]

FWIIW, I built GC 6.7 on a RHEL 3 (Opteron) system using

  ./configure --prefix=... --enable-redirect-malloc --enable-
threads=posix --enable-thread-local-alloc
  make; make check; make install

Then, I tried running a few examples with 3 different, existing Python
binaries each pre-loaded with the libgc.so library

  env  LD_PRELOAD=.../libgc.so   

One is Python 2.2.3 included in RHEL 3, one is a Python 2.5.1 build
and is a Python 3.0a2 build, all 64-bit.  All seemed to work OK.

These are 3 existing Python binaries without any call to GC_INIT().
AFAICT, on Linux, GC_INIT is a no-op anyway.

Python/Tkinter DLL conflicts on Windows

[Russell Blau]

I have some Tkinter programs that I run on two different machines.  On 
Machine W, which runs Python 2.5.1 on Windows XP, these programs run fine. 
On Machine H, which runs Python 2.5.1 on Windows XP, however, the same 
programs crash regularly.  The crashes are not Python exceptions, but rather 
are reported by Windows as errors in pythonw.exe.  (Of course, the error 
messages themselves contain absolutely no useful information.)  This happens 
whether I run them from the command prompt or from IDLE (although IDLE 
itself never crashes).  Further, the crashes occur at unpredictable times; 
sometimes the program will crash almost immediately upon startup, while at 
other times it will run for a while and then crash.

Also, I'm not sure whether this has anything to do with my problem, but 
Machine H also has Python 2.2 installed on it, while Machine W does not.

I recall seeing a message at some point that suggested that conflicts in the 
MS VC runtime DLLs might cause this sort of problem, but I haven't been able 
to find that information through a search, so I'm not sure which particular 
DLLs to look for.  Any help in tracking down the source of this problem

Re: missing pydoc gui

[Bernard Delmée]

I see what you mean, having started my fedora8-live image under
virtualbox. -g support is apparently not there with this
distribution, oddly enough. Perhaps you should post your
question on a fedora support forum.

Under the live cd (hence probably with a smaller selection of
available packages than you have), if I try the following
at the interactive python prompt, I am getting "No module named
Tkinter"

 import pydoc
 pydoc.gui()


You probably discovered this already, but you can at least
launch "pydoc -p 1234" and view the python doc by pointing
your browser to localhost:1234. The small tkinter gui normally
invoked by "-g" would add a handy search box to this viewer...

The main python doc page points to the following search link:
http://starship.python.net/crew/theller/pyhelp.cgi
which looks similar enough to what "pydoc -g" would offer.

Thanks for your reply even it was not really helpful.
Of course some attempts to generate html from tabular data are behind
me. I am trying to find help here, because I think I am not the first
one, who is trying to "generate" html tables.

The purpose of my effort is to automatically and repeatedly read ŚQL
table and save the output of the SQL SELECT to the file in the html
format. Such a "reports" can be read by user using web browser later
on.

I was just trying to find if somebody here can point me to the
existing tool, which is suitable for such a task.

Anyway thank you for trying me help.

Good point.  Not that I am willing to risk it (just using the pdf is not such a 
bad option)  but I am wondering if it would make sense to create a ramdrive for 
something like this.  if memory is needed, swap would happen, which should be 
better than creating files.

Thanks for the suggestion.  I had forgotten that pickle by default has

If you look at the bytecode generated, this doesn't seem possible:

>>> def f():
... a = ([1],)
... a[0] += [2]
...
>>> import dis
>>> dis.dis(f)
  2   0 LOAD_CONST   1 (1)
  3 BUILD_LIST   1
  6 BUILD_TUPLE  1
  9 STORE_FAST   0 (a)

  3  12 LOAD_FAST0 (a)
 15 LOAD_CONST   2 (0)
 18 DUP_TOPX 2
 21 BINARY_SUBSCR
 22 LOAD_CONST   3 (2)
 25 BUILD_LIST   1
 28 INPLACE_ADD
 29 ROT_THREE
 30 STORE_SUBSCR
 31 LOAD_CONST   0 (None)
 34 RETURN_VALUE

BINARY_SUBSCR puts a[0] on the stack, it has no way to know that a[0]
will be changed in place.  To allow an exception to be thrown before
the in-place modification of a[0], there should be a new bytecode
instruction, say BINARY_SUBSCR_WITH_A_VIEW_TO_CHANGE_IN_PLACE, which
checks that the subscriptable object supports STORE_SUBSCR (;-).

Yes.  I didn't realise this before you mentioned it, but the culprit
here seems to be the augmented assignment which acts differently on
mutable and immutable objects:

b = a  # say a is immutable
a += c # equivalent to a = a + c
b is a # -> False

b = a  # Now say a is mutable
a += c # equivalent to a.__iadd__(c)
b is a # -> True

OTOH augmented assignent are a slight optimisation:

a[i] += 1

will look for the value of a and i only once and duplicate them on the
stack, whereas

a[i] = a[i] + 1

will need to resolve a and i twice (which can be costly if a and i are
globals)

Instead of being upset about cutting your word (which was not my

statement concerning the problem I mentioned: Having an object being
created by one MSVC runtime, msvcr80.dll and passing it to another

I do get your point, but your point is maintaining compatibility
between two different *versions* of a DLL/Program.  I am talking about

Thanks for the tip.  I'll read up on the csv module and use that
instead.  I'm already running into errors with null values, etc... and
I believe some of the data in this DB will have commas, so this will
be a much cleaner way of doing things.

As usual, the python standard library has functions that do what you
want! Using the csv module will help you avoid trouble when your data
contains commas or control characters such as newlines.

import csv
help(csv)

Suggests this code:
import csv
csv_file = open('output.csv', 'w')
csv_writer = csv.writer(csvFile)
csv_writer.writerows(cursor.fetchall())
csv_file.close()

Hello,

I was able to figure this out by using join to convert the tuples into
strings, and then have those write to the filehandle:

csvFile = open("output.csv", "w")
for row in cursor.fetchall():
csvFile.write(','.join(row) + "\n")
csvFile.close

Python (when installed with "for everyone") is not (just) an
application, it's a runtime. I know that Microsoft has totally dropped
the ball on handling shared libraries and has recently thrown up its
arms and just said that all apps should ship with everything they need
("Don't use shared libraries any more, versioning is hard") but that's
not applicable to Python *the runtime*. system32 is precisely the
correct spot for it, when installed by an administrator, as a system
runtime.

Note that "for me only" Python, doesn't install to there.

interactive mode in python with ctypes???

[digitnctu]

Dear all:

 I am coming with problem, to apply ctypes under interactive mode
in python.

 libdll.dll is a third-party library. The below code segment will
run well under the batch mode(ie. python test.py 11060)
 but when I type sequencially it doesn't work as usual.  Can any
give me a hand??

# file test.py begin
  from ctypes import *
  lib = CDLL("libdll.dll")
  def evCb(ev, clData, caData):
  print "event: ", ev,"=>" , string_at(caData)

  def run(port):
  libinf = lib.libCreate(0)
  lib.libConnect(libinf,port,0,0)
  evfptr = CFUNCTYPE(None,c_char_p, c_void_p,c_void_p)
  lib.libCltAddEventCallback(libinf,"AllEvents",evfptr(evCb),0)
  result = c_char_p()
  libbuf = raw_input("lib>")
  while libbuf != "quit":
  lib.libCallCommand(libinf,libbuf,0,pointer(result))
  print "result: ",result.value
  if libbuf == "Exit":
  break
  libbuf = raw_input("lib>")
  lib.libDestroy(libinf)
if __name__ == "__main__":
  import sys,string
  run(string.atoi(sys.argv[1]))
  # file test.py end

 I type in interactive mode of python as below:

 from ctypes import *
 lib = CDLL("libdll.dll")
 def evCb(ev,clData,caData):
 print "event: ", ev,"=>" , string_at(caData)
 libinf = lib.libCreate(0)
 lib.libConnect(libinf, 11060, 0,0)
evfptr = CFUNCTYPE(None,c_char_p, c_void_p,c_void_p)
lib.libCltAddEventCallback(libinf,"AllEvents",evfptr(evCb),0)
result = c_char_p()
lib.libCallCommand(libinf,"somecmd",0,pointer(result))
lib.libDestroy(libinf)

Uh, not the man page... the output of "pydoc pydoc."  Here's a snip:


Or, at the shell command line outside of Python:

Run "pydoc " to show documentation on something.   may
be
the name of a function, module, package, or a dotted reference to
a
class or function within a module or module in a package.  If the
argument contains a path segment delimiter (e.g. slash on Unix,
backslash on Windows) it is treated as the path to a Python source
file.

Run "pydoc -k " to search for a keyword in the synopsis
lines
of all available modules.

Run "pydoc -p " to start an HTTP server on a given port on
the
local machine to generate documentation web pages.

Run "pydoc -w " to write out the HTML documentation for a
module
to a file named ".html".

Module docs for core modules are assumed to be in

http://www.python.org/doc/current/lib/

This can be overridden by setting the PYTHONDOCS environment
variable
to a different URL or to a local directory containing the Library
Reference Manual pages.  .

If nothing else, it'll help you learn more, and may also help you

That's the weird part.  The man page for pydoc doesn't mention -g as a
supported option and the output of pydoc -g just prints out the usage/
options information -- -k, -p, -w are the options.  As if the version
of pydoc I have is built without gui support.

Writing Oracle Output to a File

[t_rectenwald]

Hello,

I attempting to execute an Oracle query, and write the results to a
file in CSV format.  To do so, I've done the following:

import cx_Oracle
db = cx_Oracle.connect('user/[EMAIL PROTECTED]')
cursor = db.cursor()
cursor.arraysize = 500
cursor.execute(sql)
result = cursor.fetchall()

The above works great.  I'm able to connect to the database and print
out the results as a list of tuples.  Here is where I get lost.  How
do I work with a "list of tuples?"  My understanding is that a "list"
is basically an array (I don't come from a Python background).  Tuples
are a "collection of objects."  So, if I do...

print result[0]

I get the first row of the query, which would make sense.  The problem
is that I cannot seem to write tuples to a file.  I then do this...

csvFile = open("output.csv", "w")
csvFile = write(result[0])
csvFile.close

This generates an exception:

TypeError: argument 1 must be string or read-only character buffer,
not tuple

So, I'm a bit confused as to the best way to do this.  I guess I could
try to convert the tuples into strings, but am not sure if that is the
proper way to go.  Any help would be appreciated.  I've also seen a
csv module out there, but am not sure if that is needed in this
situation.

Best Regards,
Tom

Re: CPython and a C extension using Boehm GC

[MrJean1]

It depends on how the GC inside the extension is built.  If it is a
drop-in replacement for malloc, then GC *must* be loaded and
initialized upfront if possible.  There is no need to memcpy anything
between Python and the extension.

However, if GC does not replace malloc, etc., then GC-ed memory is
only used within the extension.  GC_INIT can be called when the
extension is loaded and memcpy-ing between Python and the extension is
mandatory.

There are other details to consider.  For example, on some platforms,
GC *must* be initialized from the main executable.  That may preclude
both scenarios, altogether.

Re: missing pydoc gui

[Bernard Delmée]

FWIW I am using 2.4.4 under debian etch and 2.5.1 under windows XP,
and pydoc seems to support the -[pgkw] flags under both versions.
When trying -g under debian, I am getting a stack-trace and a message
inviting me to install the python-tk package.

Does "pydoc -g" provide any feedback on your installation?

One nice alternative for python standard doc is the .CHM file
provided at python.org. You can use the "xchm" viewer under linux.

state of XSLT2/XPath2 or XQuery in CPython

[Christof Hoeke]

hi,
I was wondering if there is any way to use XSLT2 or maybe even XQuery 
with "normal" CPython. Using Saxon/XSLT2 with Jython is no problem (I 
have not tried Saxon.NET with IronPython but suspect no problem?) but I 
could not find any way to use XSLT2 or XPath Features with CPython. All 
the usual suspects 4suite or libxslt (via lxml) seem to have no support 
yet. Is there any hope I oversaw something?

Would be especially interesting for a WSGI application, so a more or 
less complicated hack via CPython->Jython->Saxon and back would probably 
not be very useful (if that is possible at all).

thanks!
Chris

Geodetic software development

[Fred]

Dear software developer,

GeoDLL supports the development of geodetic software on various
platforms by providing geodetic functions. GeoDLL contains precise
functions of the themes 2D and 3D coordinate transformation, geodetic
datum shift and reference system conversion, meridian strip changing,
user defined coordinate and reference systems, distance calculation,
Digital Elevation Model and map function.

GeoDLL enables the program developer to perform professional grade
coordinate transformations:

The current and many historical Coordinate and Reference Systems of
all States of the European Union (EU) including the eastern extension
from April 2004 and other European Systems.
The US- and Canadian State Plane Coordinate Systems (SPCS) on NAD27
and NAD83 and other Coordinate and Reference Systems of the North
American Continent.
The Coordinate and Reference Systems of the Australian Continent.
A lot of Coordinate and Reference Systems of other Continents.
All world-wide used Coordinate and Reference Systems.
The German Coordinate and Reference Systems of the old and new Federal
States, the 40 Prussian Soldner Land Registers, the German Lagestatus
and exact Reference Systems of the Federal States of Germany.
User-defined coordinates systems, local reference systems and earth
ellipsoids can be defined on base of the earth half axis and seven
transformation parameters (Helmert) or three transformation parameters
(Molodenski).

GeoDLL comes with extensive documentation and works as DLL file with
many commonly used programming languages or it can be used as C++ or
CA-VO source code. The functions of GeoDLL are multithreading ready.
The DLL is written with the programming language C++. Thus a very fast
performance, a compact code and a high running stability are reached.

Clother information you can find on the site

Hi Bernard,

The keys aren't integers 0...n here, they're 1, 2, 3, 4, L, R, T, D,
TL, TR, BL, BR in the code, so a dict is preferable to a list.

Incidentally Katie: is 'D' a typo? It should be 'B' for consistency.

Also, functions can be passed arguments, and doing so is preferable to
passing information via global variables.

So
def LoadMaterial(loader):
   ...
sand = LoadMaterial('Sand')

Is a lot better than

def LoadMaterial():
   ... code using 'loader'
loader = 'Sand'
sand = LoadMaterial()

 Use subprocess.

 Trying to eliminate popen because of the overhead when running

I have the feeling you just go by your feelings. Which is always a bad

M'I.5 Perse cution Mol estation du ring T ravel

[mfimei]

MI5 Persecution: Molestation during. Travel

MI5s persecution of me varies. in intensity. Since 1990 it has been steady
for perhaps 80% of the time; there was. a notable quiet period in 1993, and
another. quiet period in Jan-Feb 1995, as well as a hiatus in the first two
months of 1999.. It puzzles me that they cease and restart, seemingly
without. any logic or reason. But one aspect of MI5s activities against me
which is relatively predictable. is this weeks articles topic, which is
Molestation during Travel. Almost. every time I cross the Atlantic, go to
the Continent or even try to enjoy a holiday in this country, you can. bet
that MI5 will be there doing their utmost to wreck it. all.

This aspect of the. harassment is particularly relevant as I will be
travelling to Europe again in. a months time, with naturally the Minidisc
recorder in tow; so it will be interesting. to see if I can record the
abuse. which will almost certainly take place, either on the Tube going to
the airport, at the. airport, on the flight, in the terminal building - MI5
have previously instituted instances of abuse at. each of these locations,
so well see how much taxpayers money they waste this. time, and whether it
will. prove possible to capture their abuse on minidisc.

Read about the MI5. Persecution on the Web

June 1992 in Polands mountain resort of. Zakopane

The persecution started in. June 1990, and for the first two years I stayed
in the UK apart from a couple of brief day. trips to Calais. By the summer
of 1992 Id. had enough of being cooped up in England with abusive fellow
employees egged on by an abusive secret police service, and decided. to
spend 10 days in. southern Poland, on what was intended to be a holiday at
the mountain resort town. of Zakopane.

Unfortunately the psychopaths of the Security Service were not willing. to
allow me to. enjoy a holiday in peace and quiet. The journey to Zakopane
was by coach from the meeting point at Londons Victoria. coach station
(National Express) followed by ferry followed by another coach. across
Europe. As we left Victoria a. youth and his girlfriend started a loud
tirade of abuse directed at "this bloke", where. the "bloke" was never
named, but. it was very clear that the "bloke" was myself. The youth said
"they" had "found. somebody from his school, and he was always really
stressed at school, a. real psycho". Again, the label "they" was not
elaborated on, but it was clear. that "they" = the persecutors from
MI5. The. boy also said, "he was in a bed and breakfast for only one night
and they. got him". By a not unexpected coincidence I had been in a B&B in
Oxford a. week previously, which had been booked from work; other things
lead me to. the conclusion that the company's offices were bugged for most
of the 2 1/2. years that I was there, so "they" would have known a room in
the B&B had been booked. After a few minutes of this I went. back to where
they were. sitting and asked where they were travelling. The boy named a
village. in France, and the girl's giggling suddenly ceased; presumably it
permeated to her brain. cell what the purpose of the boy's abuse was.

It is now very clear to me that MI5 were trying to have. me incarcerated,
assaulted or killed on. this trip across Europe. The degree of verbal
violence inescapably leads to this conclusion. When we arrived. at our
destination, it became clear that many people, both in our tour group. and
its guide, and among the ordinary residents. of the town, knew there was a
movement under way to "get" me.. MI5 employed many people and significant
resources for an action which they knew would only. take a maximum of ten
days. A commercial operation would never have. felt able to waste such
resources on such an unproductive and. temporary action; only a
state-sponsored, taxpayer-funded entity like the Security. Service would be
able to be. so wasteful.

To give some examples of what happened in those ten days; I was walking. in
some. woods outside the town, when a Polish woman, looking at me, said the
English "shit" in a strongly Polish-accented voice. For. the first three
years 1990-92 MI5. had been trying to force this word on me. Another
example; I was walking near. my "hotel" when a mother said laughing to her
child, "a wiesz ze to prawdziwy wariat" which means "you know. hes a real
madman". And the "TV reacting" happened. there too; on Polish TV, a bemused
looking journalist said to another,. "to jest sprawa Anglikow", which means
"its the concern of. the English", in other words, none of our business,
despite. what the English are trying to force down our throats.

Just before we left for home, I went with some others from our group to. a
nearby bar. There a man shouted at me the same sexual obscenity which. MI5
have constantly thrown at me. these last three years. I think MI5 try to
justify their various terms of abuse by repeating them at me. until I say
them, either. while conscious or while talking in my sleep; a

MI5 Persecution: BBC Newscasters Lie & Deny. They're Watching Me

Central to the persecution campaign waged against me. for some nine years
now by the Security Service is their use of the. media, and in particular
the broadcast media, to make clear. to me that I am under surveillance and
being watched within my own home, even by BBC newscasters while. they read
the news. This is. really an act of arrogance; MI5 and their tools in the
television and radio are so sure that they. can never be caught, that they
have many times made explicity clear on. broadcast programmes that they are
as capable of. seeing me as I am of seeing the broadcast pictures. Even
when they have known I am taping the programmes they. still carry on this
practice; for examples of TVand. radio presenters caught "in action", see
the Evidence area of my. website.

It. started with a Newscaster, and it continues with Newscasters today

The very first incident in the story. started with a reaction by an ITN
newscaster, Sue Carpenter,. in June of 1990, almost nine years ago now. She
reacted to what she. saw in my living room at home as she read the news. My
mother had brought an apple for me into the. room, whereupon the newsreader
smirked and giggled, apparently finding this. funny. I couldn't believe
what I was seeing. I carried on watching news and. other television
programmes to see if presenters would. show signs of "interactive
watching";. to my surprise, this happened again and again. Unfortunately, I
did not have my wits sufficiently. about me to videotape these programmes,
and it is now almost impossible to obtain recordings dating back. to 1990.

However, I have been busy recording. everything Ive watched the last couple
of years, and the. taping has yielded some nuggets, which you will find if
you point your Web browser. at the "evidence" area of my website, whose URL
address is given above. Strangely it is not particularly the BBC. who are
"after. me" at the moment (with the exception of occasional fire from
Nicholas Witchell), but. that supposed paragon of virtue and decency Jon
Snow of Channel Four. TV News (he actually works for ITN), who once claimed
hed turned down MI5s offer of. a tax-free salary. I will cover Snows recent
actions in a future. article.

BBCs. Hidden Shame

The first ever. Usenet post (internet newsgroup article) on the subject of
the MI5 bugging / BBC watching occurred, as stated in a. previous article,
in early May. 1995. It is reproduced here;

Date:. Thu May  4 18:27:24 1995
Newsgroups:. alt.conspiracy
Subject: BBC's. Hidden Shame

Remember the two-way televisions in George Orwell's 1984?. The ones which
watched. you back? Which you could never get rid of, only the sound could
be turned. down?

Well. the country which brought Orwell into the world has made his
nightmare follow into the world after him. Since 1990 the. British have
been. waging war against one of their own citizens using surveillance to
invade privacy. and a campaign of abuse in the transmitted media in their
efforts to humiliate. their "victim".

I suppose "BBCs Hidden Shame" is more of a. wish than a fact. It may be
hidden, but. the BBC and other media and security organisations seem to
have no shame whatever in their anti-social, not to say. criminal,
actions. Nor do the general public, who. seem quite happy to parrot the
vilest obscenities without much hesitation. or apparently thought.

Martyn. Lewis, Nicholas Witchell and the rest

Most of the harassment occurred in. 1990-92, when I wasnt making any
recordings, and the BBC wont release copies. of current affairs programmes
from that period so although I can remember there were. many incidents
in that time, even many specifics, I cant dig up the actual programmes. to
flesh out the. bones.

This year, there has been at least. one incident with Nicholas Witchell as
newsreader, which. I have successfully recorded and digitized,
i.e. converted into a computer Quicktime movie file. This has not. yet
found its. way onto my website (Im a busy man, dontcha know) but you can be
sure I will. let the readership of these articles know when that clip makes
it onto the web. The Witchell clip was recorded on Saturday 10. April 1999
at. 7pm, and shows Witchell trying to restrain his features from collapsing
into a smirk. First his upper. lip quivers for several minutes, then with
the non-excuse of a non-joke his. entire face twists into a grin. It looks
as if he finds me so funny, that he allows. himself to submerge any
pretence. at professionalism in a sea of MI5-inspired sarcasm and
harassment.

M.I'5`Pers ecution - Four Years of MI 5 Persecut ion Pos ts on Inter net Newsgrou ps

[eivmvmvm]

Four Years of. "MI5 Persecution" Posts on Internet Newsgroups

For approximately the first three. years of the MI5 persecution, from June
1990 until late 1992, I kept as quiet as possible, in. the hope that by not
reacting, MI5s interest in me would. decrease and they would simply go away
of their own accord. This is the sort of behaviour some. people employ
against bullies; if the bullies arent getting a reaction, then. they might
simply. go away and victimize someone else.

Unfortunately, this tactic didnt work. The quieter I. became, the more
shrill and hysterical the noise. from the Security Service operatives. For
about two years I didnt watch TV. news at all. Yet this only heightened
their obsessed fixation; they continued to. follow me wherever I went, they
continued to induce harassment at work. by managers and fellow workers, and
they continued to encourage me to commit suicide. They seemed to. regard my
refusal to react as a crime which they would have to "put right" by. ever
more. extreme forms of abuse.

Finally, in 1995, I changed tactics. radically. Since late 1994 I had had
accounts with. internet providers in Ontario, Canada. I discovered the
cornucopia of internet newsgroups,. on every topic from consumer
electronics, to politics and legal topics, and I discovered. online
services such as Compuserve and. AOL. In May 1995, I made the first posting
to the conspiracy newsgroup, on. the subject of "BBCs Hidden Shame".

BBC's Hidden. Shame

The internet newsgroup discussion, which has now reached. its fourth
anniversary, started with an article in alt.conspiracy,. which I reproduce
here.

Date: Thu May.  4 18:27:24 1995
Newsgroups:. alt.conspiracy
Subject:. BBC's Hidden Shame

Remember the. two-way televisions in George Orwell's 1984? The ones which 
watched you
back? Which you could never get rid of, only the sound could be. turned down?

Well the country which brought Orwell into the world has made his. nightmare 
follow into
the world after him.. Since 1990 the British have been waging war against one 
of their
own citizens using surveillance to invade privacy and a campaign of abuse in. 
the
transmitted media in. their efforts to humiliate their "victim".

And the most remarkable thing about it is that what. they do is not even 
illegal - the
UK has no laws to protect the privacy of its citizens, nor does. it proscribe 
harassment
or abuse. except in the case of racial abuse.

A lot of people in England know this to be going on, yet so far they have. 
maintained
perfect "omerta"; not a sound, not a squeak has. escaped into the English 
press, and for
all the covert harassment absolutely. nothing has come out into the public 
domain.

Have the British gone mad? I think we. should be told

At this point, I did not name. MI5 as my persecutors. I was still unsure
that they were the ones responsible for the. "psychological terrorism". In
followup posts however I did name them; and the persecutors have. never
denied the claim; so I think my guess is valid.. (The Security Service
Tribunal in 1997 have said "no determination in your favour was. made", but
it is a well. established fact that MI5 lies routinely to the Tribunal
which has never found in favour of a plaintiff, so no conclusions. can be
drawn from. this.)

This first post was made to alt.conspiracy, but further posts were. made to
the. UK-local newsgroups, in particular uk.misc but also uk.legal and
uk.politics (which is now called. uk.politics.misc). Some time ago I tried
to take the battle to. the Compuserve forums, UKPOLITICS (which is now
called UKCURRENT -. current affairs), but my articles were censored by the
forum operators. Such censorship is impossible on the internet. newsgroups.

Somewhere between. 0 and 100%

The last few days there have been no clear. recordable instances of
abuse. However, while. travelling on the Underground, while walking around
near my home and going. to friends homes, I am constantly troubled by
thoughts that those people over there might be about to get at me;. that
the couple sitting in the opposite seats laughing are in fact. laughing at
me; et cetera, et. cetera.

A comment by a scientist to the. BSE inquiry sticks in my mind. He
described the. possible scale of the epidemic as "between 0% and 100%". It
might not be. happening, it might not happen at all, to any discernable
degree or it might. be total. Without clear recording, which seems to
have. become impossible the last couple of weeks, there is no way of
knowing whether the harassment really. is continuing, whether we have
entered a temporary hiatus,. or whether perhaps it has perhaps stopped for
now.

But. for the time being I think there arent any reasons to dicontinue these
faxes. I only. re-started them six weeks ago in response to a resumption of
MI5 harassment; and I think I will need to be more convinced. of absence of
persecution before. I discontinue my complaints.

The Newscasters are still. watching

In the last. few weeks there have been at least a couple of fairly overt
instances of "interactive watching" by newscasters. I reported. this in a
previous "MI5 Persecution. Update".

These instances are really very rare compared to 1990-91, when there. were
many dozens of such occurrences. Undoubtedly. the reduction is due to my
practice of videotaping everything I see. Recently I. had the opportunity
of showing this years "happenings" (Jon Snow/Nicholas Witchell). to my
psychiatrist, and he agreed. that in both cases the newscasters were
expressing merriment without visible cause, and that objectively it. might
be possible for my claims to. be true - although of course other people
reported similar thoughts to him, and this thinking. is usually a symptom
of. illness.

the. surveillance itself, and in the technical side of the delivery of
information from my home to TV studios. for example, if the "interactive
watching" were. happening as described. He voiced these thoughts without
any prompting from me; but both. I and other observers had arrived at
pretty much. the same conclusions, some years ago.

I saw a team of. four men at Toronto Airport in 1993

To carry out the surveillance alone, full-time, would employ four or. five
men, or. their equivalent in terms of man-hours. Each man would "work" an
eight-hour shift,. so you would need at least three men doing the
surveillance, plus. a connecting link / manager. An indicator that this
estimate is correct. arrived in 1993, when I was accosted by one of a group
of four men at Toronto Airport; he said, laughing, "if he tries to. run
away well find him". Plainly these. were the men who had been involved in
the intrusive surveillance of me for the preceding. three years.

On other occasions, I have seen the. same man on two or three occasions. On
one such. occasion, at Ottawas Civic Hospital in November 1996; he gave his
name to the doctor as "Alan Holdsworth" or. some such; my hearing is not
very good sometimes and. I am not sure of the surname, although I am sure
"Alan" was his first name. I saw exactly the. same man again in Ottawa, at
the airport,. in July 1998. Obviously, other people must be "

Knowing CGI is certainly not the worst starting point wrt/ web 
development - I whish more PHP 'programmers' had the minimal 
understanding of the HTTP protocol required to write a CGI script (and 
any serious web app FWIW).

Django or Pylons are probably what you're looking for. The first one is 
the more mature, stable, and well documented, and the second one the 
most promising IMHO. If you're new to both web development and Python, 
I'd actually recommand Django.

The HTTP 1.1 RFC !-)

Seems fine to me - at least understandable, and that's the important

MI5. Persecution Update: Friday 16 April, 1999

BBC newscaster Nicholas. Witchell cant stop himself laughing

During 1990-91 there were. very many instances of "interactive
television" where newscasters and other. TV presenters saw on a screen
before. them what was happening in my home, and reacted, frequently by
laughing at. me. During this period I unfortunately did not record these
programmes. For the last year or two, I. have been recording everything I
watch,. and there has been a drastic decrease in such incidents.

However, on occasion, television presenters do. still engage in
"interactive watching" and. react to what they see. This has been evident
with Jon Snow of Channel Four News recently - a particularly. interesting
case, since it has been established that he cannot. be corrupted by money
(it is well-documented that MI5 offered him a. tax-free salary and he
turned. them down). I wonder what device MI5 are using to encourage him to
do. the "interactive watching"?

On Saturday 10 April 1999. at 7pm, Nicholas Witchell on BBC2 News reacted
when he saw that. I was watching the programme, and I have his reactions
stored safely on. videotape. I have watched this tape several times and I
am entirely confident that my evaluation of his. reactions is correct. For
several minutes his upper lip quivered in mirth as. he attempted to keep a
straight face. Then finally his self-control evaporated through. the excuse
of a weak joke and. his face collapsed into a grin.

The strange thing is that I dont know why he was. laughing at me, what I
had done recently to "deserve" to be laughed at.. The MI5 persecutors
usually. manage to invent some justification as to why people should laugh
at and/or abuse me ("hes an X", "it was so funny" etc), so. Mr Witchell
could have been laughing for any number of reasons. Perhaps he found. the
views I have been expressing. in these articles amusing? I suppose if youre
paid enough money and ordered to. laugh then even the most innocuous thing
becomes. funny.

Jon Snow. of Channel Four News cant stop himself smirking, either.

On 12 February 1999 I was watching Channel Four. News presented by Jon
Snow.. As usual, I was recording the programme, so that if anything out of
the ordinary happened, Id be able to. go back and watch it again.

Now, Jon Snow, by his own claim, is. uncorruptible. He says he turned down
an offer of a substantial tax-free salary from MI5 -. they wanted to make
him their mouthpiece, and. he told them where to get off.

So you will be most. surprised to learn that Jon Snow "interactively
watched" me that evening, and. on many other evenings. Approximately
fifteen minutes into. the programme, he announced that the US President
would be making a live appearance at. about 7.30pm; I looked at the clock
on the mantelpiece;. and Snow saw me looking at the clock, and visibly
tried to suppress a. smirk.

Uncorruptible, are you, Mister Snow? If not money, then why. are you
watching me, Mister. Snow? Are they forcing you to watch me? Cant you turn
the monitor off,. Mister Snow?

refuses. to help.

Comparing the MI5 Persecution with German. "Final Solution"

It might seem. offensive to compare the mass murder of millions of
civilians in wartime with the peacetime persecution of. merely one
person. Yet the comparison has. been coursing through my mind for several
years now, because the brutality of. German intent to "sub-humans" is very
much comparable to the brutality of British intent to. someone they
vituperate and term "not up to British standards". The methods may. differ,
but the persecutors mindset is. the same.

The. Germans first targeted the mentally disabled, too

During WW2 millions of ethnic Russians, Poles, Jews, mentally. ill, gypsies
and other minorities were. rounded up and murdered in purpose-built camps
by the German regime, in the name of "racial. superiority". Fifty years on,
the British Secret Police, MI5, instituted a campaign of. mass
hysteria; but in their cowardice,. limited their activities to one single
victim.

It is instructive to note that. the early German "cleansing" effort was
directed primarily not at Jews, but at the mentally ill. The. Nazis set up
the T4 project in the thirties to "cleanse" away 70,000 mentally. disabled
people, including schizophrenics and epileptics. After WW2. the Jews with
their media influence used the reaction from. the holocaust to roll back
anti-semitism in the Western countries; however, the. mentally ill are
today still. a persecuted group in the modern Western world as they were
under the Nazis (the current Jewish home secretary in the UK. intends to
bring in laws for incarceration without. any criminal charge for some
mentally ill people - he protects his own minority,. but does nothing

Markup should only convey semantic informations - presentation is best 
done using css. IOW : presentation-related stuff in the html should be 
restricted to css class declarations.

As I said, wrt/ html generation, there are quite a lot of possible 
solutions - FWIW, generating an html table from a set of tabular data is 
nothing difficult. So without more information on the context, it's hard 
to give any valuable advice. Are you doing a web application ? If yes, 
you should already use a template engine, so just use it. Else, why is 
your application generating html at all ?
