should I distribute .pyc files?

[akbar]

Hi,

I am creating not-so-important opensource application written in python
for Linux. I have two files python source in src directory, named
blabla1.py and blabla2.py. There are byte compiled files too, named
blabla1.pyc and blabla2.pyc. Should I distribute these files (pyc
files) to users? If I don't distribute them, and user installed my
application into /usr (not writable by normal user) then run it as
normal user, off course, the python cannot make byte-compiled version.
Will my program runs slower in user computer then in my computer
because I have byte compiled version?

Thank you.

trouble getting google through urllib

[Dr. Locke Z2A]

So I'm writing a bot in python that will be able to do all kinds of
weird shit. One of those weird shit is the ability to translate text
from one language to another, which I figured I'd use google translate
to do. Here is the section for translation that I'm having trouble
with:

elif(line[abuindex+1]=="translate"):#if user inputs
translate
text=""
for i in range(abuindex+2, len(line)):#concantenate all
text to be translated
text=text+"%20"+line[i]

t_url="http://translate.google.com/translate_t?text='"+text+"'&hl=en&langpair=es|en&tbb=1"
print "url: %s" % t_url#debug msg
urlfi=urllib.urlopen(t_url)#make a file object from what
google sends
t_html=urlfi.read( )#read from urlfi file
print "html: %s" % t_html #debug msg
print "text: %s" % text#debug msg

This uses urllib to open the url and abuindex+2 is the first word in
the string to be translated and line is an array of the message sent to
the bot from the server. After this I'll add something to parse through
the html and take out the part that is the translated text. The problem
is that when I run this the html output is the following (I asked it to
translate como estas here):



403 Forbidden






Google  
 
Error
 

Forbidden
Your client does not have permission to get URL
/translate_t?text='%20como%20estas'&hl=en&langpair=es%7Cen&tbb=1
from this server.






Does anyone know how I would get the bot to have permission to get the
url? When I put the url in on firefox it works fine. I noticed that in
the output html that google gave me it replaced some of the characters
in the url with different stuff like the "&" and "%7C", so I'm
thinking thats the problem, does anyone know how I would make it keep
the url as I intended it to be?

Yeah, I have watched three of them and they are glaring examples of what

No it's not, because you insist on presenting only one part of the

Eh, funny, I have used wx thingy for quite some time (when it was

wxWidgets) and it's probably the worst of all crossplatform toolkits I
have ever used. So I'm not sure you'll be able to convince me here :D

Ok, now here's a question for you: if crossplatform toolkits/frameworks
are so great and automagically allow to produce superlickable and
native-looking/feeling applications on all three major platforms, why is
there so few of those applications on OS X ? 

"Because Mac users are elitists assholes" is not the good answer by the

That depends on the usage of the addresses.  If you need them as objects
with "behavior" i.e. methods then you would write an `Address` class.  If
you can live with something more simple than a `dict` as `address`
attribute of `Employee` objects might be enough.

BTW you wouldn't create a nested `Address` *class*, but hold a reference
to an `Address` *object* within the `Employee` *object*.

class Address(object):
def __init__(self, city, state):
self.city = city
self.state = state

class Employee(object):
def __init__(self, name, title, address):
self.name = name
self.title = title
self.address = address

employees = { 'Joe': Employee('Joe',
  'Developer',
  Address('Detroit', 'Michigan')) }

def employee(name):
return employees[name]


def main():
person = employee('Joe')
print person.title
print person.address.city
print person.address.state

How would I create an class with a "Person.Address.City" property?

[Jamie J. Begin]

I'm very new to the world of Python and am trying to wrap my head around
it's OOP model. Much of my OOP experience comes from VB.Net, which is
very different.

Let's say I wanted to create an object that simply outputted something
like this:

>>> import employees
>>> person = employee("joe") # Get Joe's employment file
>>> print employee.Title # What does Joe do?
Developer
>>> print person.Address.City # Which city does Joe live in?
Detroit
>>> print person.Address.State # Which state?
Michigan

To do this would I create nested "Address" class within the "employee"
class? Would it make more sense to just use "print
person.Address('City')" instead?

Thanks for your help!

The fact that this doesn't do what dedent() does makes it not useful.
Stripping all leading spaces from text is as easy as calling lstrip() on
each line:

text = '\n'.join([line.lstrip() for line in text.split('\n')])

alas, that isn't what I am looking for, nor is that what
textwrap.dedent() is intended to do.

I am facing a problem with a script that i had written to automate
opening a website and signing on to it. It was running fine for a long

but when i execute the whole script it gives this error:

Umm, no, that's why I wrote "eight spaces (as opposed to 'correct' tab
stops)".

In either case, though, it'd be hard to know how to replace the tabs, so
it'd be better not to remove them in the first place.  Indeed, dedent()
would work perfectly for my cases if it simply didn't do the
expandtabs() in the first place, but there'd be some pretty glaring
holes in its logic then.

I've since written up a fairly reasonable (IMO) replacement though, that
started with textwrap.dedent(), removed the expandtabs() call, and 
Does The Right Thing with tabs vs. spaces (e.g. it doesn't treat a tab
at the beginning of a line as the same as eight spaces).

Class property with value and class

Hi,

Is is possible to have two classes, ClassA and ClassB, and
setattr(ClassA, 'xx',ClassB), AND to then have ClassA.xx store an
integer value as well, which is not part of ClassB?

e.g. If ClassB has two properties, name and address:

ClassA.xx=10
ClassA.xx.name = 'John'
ClassA.xx.address = 'Sydney'.

etc?  I've no idea if this is possible or desirable.

The underscore, in the interactive interpreter, stands for
the result of the last statement.  So in the above, you can 
think of it as the "name" of the string without spaces after 
the commas, on the previous line.

Note that to fix pathological stuff like:

s = "asasd, oipuopioiu,   this is bad shit,\tiuiuiu,,, , "

you will have to do more work than the simple solution
above...

I am constantly amazed by how different we all are, when
I read the diverse solutions to such a seemingly simple
problem - and the nice thing is that they all work...

Have a good look at Peter Otten's solution - try to 
understand it - it uses most of the very useful Python
functions.

Lightweight embedding of Firefox Gecko into application whose top level is Python--possible?

[Kenneth McDonald]

Sorry for crossposting to several lists, but from what I can tell, what 
I want to do may involve several different areas of expertise. (None of 
which I have :-( )

I'd like to use Gecko as the UI for an application mostly implemented in 
Python. Ideally, I'd like to somehow come up with a Python module that 
wraps the Gecko, so that I can:

1) Create windows whose content is drawn by Gecko.
1) Dynamically manipulate what is shown by Gecko.
2) Respond to mouse events and keypresses occurring on the window Gecko 
is in.

I really don't need, or want, anything beyond this. Presumably Gecko 
does have some notion of the DOM, since it handles CSS (which I do want) 
and CSS needs the DOM to be meaningful. And I'm also assuming that Gecko 
has or requires JavaScript, in order to actually do things with the DOM, 
or at least to handle DOM events. (Or at the very least to handle mouse 
events, since key events could in theory be handled outside of the 
layout engine.) But I'd like to be able to build something with _just_ 
those features.

Given the above, using Firefox or even Xulrunner seems to be very 
heavyweight and unnecessary. It would be somewhat nice to be able to 
manipulate a XUL DOM to created panes, menus, etc. But even that is not 
necessary--so far as I can tell, DOM manipulation+CSS has the ability 
right now to do menus, scrollable sidebars, panes, etc.

I'd like to get away from the rest of the FF/Mozilla baggage (especially 
XPCOM) because:

1) I don't want to have to deal with XPCOM, chrome stuff, XUL, make 
details, XPIDL (or whatever it is), etc. etc. My brain is already too 
full. :-)
2) Even if I did want to deal with the above, I find the documentation 
for it disorganized and, more often than not, out of date. Not a 
criticism, just an unavoidable weakness of open source development with 
a large number of developers.

Given that the _only_ thing I really want to use is the Gecko layout 
engine with some sort of relatively rudimentary keyboard and mouse 
handling (I'll do all of the sophisticated handling in Python), it'd 
just be nice to be able to dispense with all of the rest of the stuff.

For the record, I do know that PyXPCOM is still being developed, and 
what little I've been able to glean suggests it's been going reasonably 
well. However, I'm not sure it will do what I want it to. It appears to 
be a way to write XPCOM components in Python, and I have no idea if that 
will allow me to just use Python in the same way JavaScript is used 
right now, which is what I want. From what little I've been able to 
track down it seems that PyXPCOM may only be the starting point for 
moving towards using Python for DOM scripting. Also, I'm not sure when 
it will actually be done. Up-to-date online info about PyXPCOM (aside 
from bug tracking) seems very sparse.

Given all of that, answers to the following questions (or suggestions 
related to the whole endeavour) would be appreciated.
1) Does this even seem feasible? Can Gecko be 'broken out' from the 
other Moz technologies to this extent?
2) Does anyone know of similar projects?
3) Can anyone point out a simple example of encapsulating Gecko in a 
small C/C++ app, and then running/communicating with Gecko from that 
code? (i.e. a Gecko embedding "Hello world") This is in some sense what 
I'd be doing, since using Gecko from Python would involve (I assume) 
wrapping Gecko in a Python-compatible C wrapper. I've come across a 
number of embedding Gecko tutorials, but nothing that starts at such a 
basic level.
4) Do I need to somehow provide/link in a windowing system of some sort, 
or do I get that with the version of Gecko appropriate for the target 
platform?
5) Will PyXPCOM let me do what I want? And is it close enough that I 
should just wait for it? (It doesn't bother me if all of the rest of the 
Moz/FF stuff is included in my app, just as long as I don't have to deal 
with it.)

Many thanks,
Ken McDonald

IMHO, none of the results is right. Either unicode string should be
rejected by raising ValueError or it should be encoded with ascii
encoding and result should be the same as
urllib.unquote(u'%94'.encode('ascii')) that is '\x94'. You can consider
current behaviour as undefined just like if you pass a random object
into some function you can get different outcome in different python

python script terminating

[Aditya Vaish]

I have a python script running on Debian sarge. It loops and walk through a
directory

 

while 1:

for dirn in os.listdir(buildpath):

if os.path.exists(os.path.join(buildpath, dirn, 'pass')) and
dirn.find(build1) != -1:

#   case 1

Do something

 

elif os.path.exists(os.path.join(buildpath, dirn, 'pass')) and
dirn.find(build2) != -1:

#   case 2

Do something

 

The script in turn calls a perl script to do something. The problem is that
the python script is getting terminated while the perl script is running and
thus the program called by the perl script is hung.

SQLAlchemy, py2exe and Python 2.5 problem?

[Karlo Lozovina]

I've just upgraded to Python 2.5, SQLAlchemy 0.3.3, and py2exe 0.6.5 
(the py2.5 version, yes).

Simple:

---
import sqlalchemy
print 'Test'
---

works when interpreted by Python, but when running it from compiled 
py2exe binary, it fails with this error:

Traceback (most recent call last):
  File "main.py", line 1, in 
  File "sqlalchemy\__init__.pyc", line 10, in 
  File "sqlalchemy\orm\__init__.pyc", line 12, in 
  File "sqlalchemy\orm\mapper.pyc", line 7, in 
  File "sqlalchemy\logging.pyc", line 30, in 
ImportError: No module named logging

Ofcourse, library.zip (in the dist directory) contains 'sqlalchemy
\logging.pyc'. After I copy logging.pyc to library.zips' root, I get 
this error:

Traceback (most recent call last):
  File "main.py", line 1, in 
  File "sqlalchemy\__init__.pyc", line 10, in 
  File "sqlalchemy\orm\__init__.pyc", line 12, in 
  File "sqlalchemy\orm\mapper.pyc", line 7, in 
  File "sqlalchemy\logging.pyc", line 30, in 
  File "sqlalchemy\logging.pyc", line 33, in 
AttributeError: 'module' object has no attribute 'getLogger'

Does anyone have a clue why this happens? And what is responsible for 
this? SQLAlchemy, or py2exe?

Thanks in advance...

I certainly hope so, but this is what I'm reacting to (from
http://www.webfaction.com/freetrac):

"We're sorry, we're not longer accepting applications for free trac/svn
accounts. People have left their Trac sites unattended and as a result
our server is being flooded with spam. We need to do some serious
cleanup and when that's done we'll accept new applications again (that
might take weeks, if not months though). "

Unless my reading comprehension skills have completely abandoned me,
they aren't saying that they are experiencing downtime. They are saying
that they have shut down the service, for weeks or months -- with no
notice (again, at least not any that I got). I can understand shutting
down projects that are dead and just accumulating spam. I can
understand shutting the whole thing down, with a decent notice so that
projects don't die with the service. This, I just don't get. I hope I'm
overreacting. I hope I can slurp up all of my tickets tomorrow and
import them into their new home at google. But I'm not counting on it.

Surprised doesn't quite cover it. Perhaps someone from python hosting

I have run that exact installer many many times and it works fine. to

>>> from Crypto.Hash import SHA256
>>> sha = SHA256.new()
>>> sha.update('message')
>>> sha.hexdigest() # sha.digest gives the raw form

urllib.unquote and unicode

[George Sakkis]

The following snippet results in different outcome for (at least) the
last three major releases:

>>> import urllib
>>> urllib.unquote(u'%94')

# Python 2.3.4
u'%94'

# Python 2.4.2
UnicodeDecodeError: 'ascii' codec can't decode byte 0x94 in position 0:
ordinal not in range(128)

# Python 2.5
u'\x94'

Is the current version the "right" one or is this function supposed to
change every other week ?

You are mostly correct. In Style.py, each style gets initialised to
refer to a module-global bunch of default objects. No copying is done.

Each member of a struct has a distinct, predefined
role. Even if they all have the same type, you
can't swap their values around without destroying
the meaning of the data. That's what's meant by
"heterogeneous" in this context -- it's not about
the values themselves, but the way they're used.

This is the kind of thing for which Python tuples
are mainly designed -- use as a struct whose
members happen to be named by integers rather
than strings.

If you still don't understand, then I'm afraid
I've run out of ideas on how to explain it.

Using DCOP from Python

[Jeffrey Barish]

The package python-dcop makes it possible to use DCOP from Python.  Does
anyone know of a tutorial for this package or an example of its use?  I
would like to use it to read a journal entry in Korganizer.  I got as far
as figuring out that DCOP offers the interface
korganizer.CalendarIface.openJournalEditor(QString text, QDate date)
but I'm having trouble figuring out how to call this function from Python. 
And will it become clear how to control whether I am reading or writing the
journal?

Tkdnd--does anyone use it?

[Kevin Walzer]

Does anyone use the Tkdnd module that comes with Tkinter to allow
drag-and-drop of Tkinter widgets in your application? (Not the binary
extension that hooks into Xdnd and OLE-dnd on Windows.) I've looked at
the various documents for Tkdnd, and it looks somewhat complicated,
particulary if you want to use it outside of the canvas widget; I've
also found very few examples of its actual use (as opposed to sample
code snippets). I'm curious if anyone is actually using it in a
production application and, if so, what your experience with it is.

I don't have a Mac, although I would certainly like one. But one of
the two authors of Dabo is a Mac user, and says that he does all his
development on a Mac, and then tests it on the other platforms. Look
at the screencasts on the Dabo site - most of them are recorded on OS
X.

OK, it's true: you don't have 100% access to the lickable Aqua stuff
that a Cocoa app might be able to use. But paged controls use native
Aqua tabs; progress bars are native Aqua bars, buttons are native Aqua
buttons... Perfect? Of course not. But stating that it sucks is a load
of crap.

Huh? Based on what I've seen on the screencasts, the apps look better
on the Mac than they do on XP. How should I judge how they "feel"?
SIzers automatically take care of font metric differences and native
control size differences.

Well, I don't think *anything* looks as good on Windows as it does on
a Mac, whether it is from a platform-specific toolkit such as Winforms
or a cross-platform toolkit like wxPython. If you want it to look as
good on Windows, you'll have to use VNC or something like that.

It looks/feels like a native app on OS X.

That was written a long time ago, and doesn't really apply anymore as a
lot of effort has gone into wxPython over the past three years getting
correctly interfaced to the OS X native API.

(Note to self: rewrite that (prescient) paragraph).

Admittedly, to some extent there is a lowest common denominator problem
inherent in any UI toolkit that tries to be crossplatform and use the
platform's native GUI. But for the most part, that just isn't the case
anymore in a practical sense.

Why not use the best crossplatform native toolkit (wxPython) and then if
you need native features that aren't provided, use ctypes or something
to get access to the native GUI? Nothing in wxPython or Dabo prevents
you from doing that.

Absolutism sucks. Please try not to be so black and white about things,

Re: writing serial port data to the gzip file

[Petr Jakes]

Maybe I am missing something. Expect data is comming continually to the
serial port for the period say 10min. (say form the GPS), than it stops
for 1 minute and so on over and over. I would like to log such a data
to the different gzip files.
My example was written just for the simplicity (I was trying to
demonstrate the problem, it was not the real code and I was really
tired trying to solve it by myself, sorry for the bugy example)

the better way how to write such a infinite loop can be probably:
= 8< =
g=0
x=0
while 1:
if not g:
x+=1
g=gzip.GzipFile("/root/foofile%s.gz" % x,"w")
data=dataOnSerialPort()
while data:
myFlag=1
g.write(data)
data=dataOnSerialPort():
else:
if myFlag:
g.close()
pring g
myFlag=0

But it looks like g.close() method does not close the file (while
trying to print the g object, it  still exists)

Re: When Closure get external variable's value?

I don't quite get what you are trying to tell us but if you think that 
in your example code:

 def testClosure(maxIndex) :

 def closureTest():
 return maxIndex

 maxIndex += 5

 return closureTest()

 print testClosure(10)

you are returning a callable function you are all wrong. This can be 
easily seen by:

 >>> type(testClosure(10))
15


The mistake is that you shouldn't return closureTest() but closureTest 
instead. The correct way would be:

 >>> def testClosure2(maxIndex):
def closureTest():
return maxIndex
maxIndex += 5
return closureTest

 >>> f2 = testClosure2(10)

 >>> type(f2)

 >>> print f2()
15

pyExcelerator question

[Gerry]

I'd like to word wrap some cells, but not others, in an Excel
spreadsheet, using pyExcelerator and Excel 2003, SP1, under XP.

The code below creates the spreadsheet, but both cells are
word-wrapped.

As far as I can tell, the second call to XFStyle() overwrites a GLOBAL
wrap setting, and affects even cells written before the call to
XFStyle.

Can anyone shed any light?

Thanks,

Gerry


from pyExcelerator import *


w   = Workbook()
ws  = w.add_sheet("alpha")

style   = XFStyle()
style.alignment.wrap= Alignment.NOT_WRAP_AT_RIGHT
ws.write(1,1,"Not wrapped" + "-" * 50, style)

style2   = XFStyle()
style2.alignment.wrap= Alignment.WRAP_AT_RIGHT
ws.write(2,1,"Wrapped" + "-" * 50, style2)

w.save("test.xls")

Ask yourself what are the names 'index' and 'self' refering to in the 
context of this function, and you'll have the answer. And if you can't 
answer, then it may be time to learn Python...

FWIW, the first version raises an exception (unless of course the name 
'index' is already bound in the enclosing scope). And the second won't 
probably work as expected with CherryPy.

The resident experts seemingly being absent for a while, I'll strike:

Yes: the first gives a runtime error and the second is OK.
I've renamed the second class to HelloWorld2 and then:

 >>> hw = HelloWorld()
 >>> hw2 = HelloWorld2()

 >>> hw.index()
Traceback (most recent call last):
   File "", line 1, in 
 hw.index()
   File "C:\Python\Dive into Python\Py\apihelper.py", line 40, in index
 index.exposed = True
NameError: global name 'index' is not defined

 >>> hw2.index()
'Hello world!'

The error message shows that the Python compiler has interpreted the 
construction 'index.exposed' to refer to a global variable 'index' that 
doesn't exist at run time. The second class succesfully defines an 
instance attribute 'exposed' as can be seen by:

 >>> print hw2.exposed
True

Oh, I'm sure you do. Now go try to run one of your Dabo apps on a Mac

Here's a hint directly taken from the Dabo homepage: "It also suffers

No, sizers are a tiny part of a much bigger problem. Sizers might be the
key to solve parts of the "look" problem, they don't address any of the
"feel" problem.

But you clearly have a point here, so let me rephrase: "Crossplatform
toolkits/frameworks suck. All of them. No exception. UNLESS you only
target the lowest common denominator, aka Windows and its Linux
followers".

Now, the OP *explicitely* said that "[his] requirement is that the
application needs to look as good on Windows as on the Apple Mac", so
the rephrasing does not apply in this case. So here's a last try:

"Crossplatform toolkits/frameworks suck. All of them. No exception.
ESPECIALLY if one of your target is Mac OS".

 From a purely logical POV, the fact that a stack implementation has

Trevor Stent: "Whitespace as a universal constant"

Re: writing serial port data to the gzip file

[jim-on-linux]

If someone hasn't already commented, 

Aside from any other problems, the file you are 
trying to write to is (opened)?? in the "w" mode. 
Every time a file is opened in the 'w' mode, 
everything in the file is deleted.

If you open a file in the 'a' mode, then 
everything in the file is left untouched and the 
new data is appended to the end of the file.

Your while loop is deleting everything in the file 
on each loop with the 'w' mode.

try, 
vfile = open('vfile', 'a')
rather than 
vfile = open('vfile', 'w')

Using windows authentication IMHO should only be used if there is an Active 
Directory/LDAP server set up against which the users are authenticated. I 
googled for 'active directory python' and came across 
http://tgolden.sc.sabren.com/python/ad_cookbook.html It seems to be very 
simple to use.

If I were to implement an authentication system like you want. I would:
1. Check to see if the local machine was part of a domain. If not then inform 
the user that they need to be.
2. Check to see if the user who ran the application is part of a specific 
group in AD.

I would assign each group a certain 'level' of privilege and accordingly let 
the user do what they should be able to do.

I hope this is a good starting point.

SQLObject 0.8.0b1

[Oleg Broytmann]

Hello!

I'm pleased to announce the 0.8.0b1 release of SQLObject. This is the first
beta of the new branch. Taking into account that it is a result of rather
large job the beta period will be prolonged. Meanwhile the stable 0.7
branch will be maintained, and there will be at least 0.7.3 release.


What is SQLObject
=

SQLObject is an object-relational mapper.  Your database tables are described
as classes, and rows are instances of those classes.  SQLObject is meant to be
easy to use and quick to get started with.

SQLObject supports a number of backends: MySQL, PostgreSQL, SQLite, and
Firebird.  It also has newly added support for Sybase, MSSQL and MaxDB (also
known as SAPDB).


Where is SQLObject

News and changes:
http://sqlobject.org/devel/News.html


What's New
==

Features & Interface


* It is now possible to create tables that reference each other.
  Constraints (in the DBMSes that support constraints) are added after the
  tables have been created.

* Added ``createSQL`` as an option for sqlmeta. Here you can add
  related SQL you want executed by sqlobject-admin create after table
  creation. createSQL expects a string, list, or dictionary. If using
  a dictionary the key should be a dbName value (ex. 'postgres') and
  the value should be a string or list.  Examples in
  sqlobject/tests/test_sqlobject_admin.py or at
  

* Added method ``sqlhub.doInTransaction(callable, *args, **kwargs)``,
  to be used like::

  sqlhub.doInTransaction(process_request, os.environ)

  This will run ``process_request(os.environ)``.  The return
  value will be preserved.

* Added method ``.getOne([default])`` to ``SelectResults`` (these are
  the objects returned by ``.select()`` and ``.selectBy()``).  This
  returns a single object, when the query is expected to return only
  one object.  The single argument is the value to return when zero
  results are found (more than one result is always an error).  If no
  default is given, it is an error if no such object exists.

* Added a WSGI middleware (in ``sqlobject.wsgi_middleware``) for
  configuring the database for the request.  Also handles
  transactions.  Available as ``egg:SQLObject`` in Paste Deploy
  configuration files.

* New joins! ManyToMany and OneToMany; not fully documented yet, but still
  more sensible and smarter.

* SELECT FOR UPDATE

* New module dberrors.py - a hierarchy of exceptions. Translation of DB API
  module's exceptions to the new hierarchy is performed for SQLite and MySQL.

* SQLiteConnection got a new keyword "factory" - a name or a reference to
  a factory function that returns a connection class; useful for
  implementing functions or aggregates. See test_select.py and
  test_sqlite_factory.py for examples.

* SQLObject now disallows columns with names that collide with existing
  variables and methods, such as "_init", "expire", "set" and so on.

Small Features
--

* Configurable client character set (encoding) for MySQL.

* Added a close option to .commit(), so you can close the transaction as
  you commit it.

* DecimalValidator.

* Added .expireAll() methods to sqlmeta and connection objects, to expire
  all instances in those cases.

* String IDs.

* FOREIGN KEY for MySQL.

* Support for sqlite3 (a builtin module in Python 2.5).

* SelectResults cannot be queried for truth value; in any case it was
  meaningless - the result was always True; now __nonzero__() raises
  NotImplementedError in case one tries bool(MyTable.select()) or
  "if MyTable.select():..."

Bug Fixes
-

* Fixed problem with sqlite and threads; connections are no longer shared
  between threads for sqlite (except for :memory:).

* The reference loop between SQLObject and SQLObjectState eliminated using
  weak references.

Yes, because I want common configuration syntax and runtime
semantics across FreeBSD, Linux, Windows, et al.  The only
semantic difference is that, on Windows, if my own association
is not found, then the Windows association will apply.  This
cannot be done in the *nix environment - at least not easily -
because there is no common association repository across the
various window managers, nor is there a startfile() type
call in the POSIX world.


This is implemented already and largely works as planned.
There are a few subtleties I want to work into the next
release, but things work as expected today...

Not at all.  It's not even generally true of Python.  Mutability is
orthogonal to containership.

arrays, files, cStringIO objects, mmap objects, thread locks, some
iterator types, etc., are mutable but do not contain Python objects
(__dict__ excepted).

tuples, frozensets, instancemethods, are immutable but do contain
Python objects.

Actually, I surely pass a string as attribute name to getattr()

getattr is acquisition-aware so you might be retrieving another thing...


The *strange* is that I get the same error even if I pass the attribute
name to the getattr() function as pure string:

getattr(container,"WorkFlowTest")
(sic!)


If you're really sure of this, I think the error may occur inside 
another function in the getattr chain.

Please note: GC is not part of CL's definition.  It is likely not part

Binding the name "split" to this result is not a good idea, because it
leads to ...

... the above line being rather difficult to read without exclamations
:-)

... and the above causes the same problem.

tcode = ttime + tcode

might be better.

Try this:

 def toEpoch(timestamp):
  datestr, timestr = str(timestamp).split(' ')
  tdate = datestr.split('-')
  ttime = timestr.split(':')
  tcode = map(int, tdate + ttime)
  epoch = timegm(tcode)
  return int(epoch)

At the moment SS doesn't allow to change the type of a variable during
its lifetime, but SS is a moving target, maybe in the (far) future it
will split it into two variables...
I'm sure Mark likes to receive practical suggestions on how to improve
SS to make it closer to Python. (And I think he likes to receive

things, like speeding up a lib written with C++, etc).

It's a wire protocol.  At one end of a socket, there's MySQL, and
at the other end, there's a client.  Neither side needs code from
the other.  The protocol is published.  So there's no license issue.

Well... sure, but that isn't the point. Here is the problem I was
trying to solve:

I wrote and maintain the 'twander' cross-platform file browser:

   http://www.tundraware.com/Software/twander/

I was working on a new release and wanted to add file associations
to it.  That is, if the user selected a file and double clicked or
pressed Enter, I wanted the following behavior (in the following
steps, "type" means nothing more than "a file whose name ends with
a particular string"):

1) If an association for that file type exists, run the associated program.

2) If an association for that file type does not exist:

a) If the file is not "executable", see if there is a "default"
   association defined and run that program if there is.

b) If the file *is* "executable", run it.


So ... all I really needed to know is whether or not the OS thinks the
file is executable.  Obvious - and this is true on most any system -
you can create the situation where the file appear executable from
the OS's point of view, but it is not actually.  But this is a pathology
that no application should really be expected to cope with...

What gave you that impression, if you don't mind my asking?

It's true that Python's built-in application scripting support
(aetools+gensuitemodule) has become increasingly broken on OS X and
should be avoided. Third-party support has been continually improving
over the last few years, however, and these days is pretty much on-par
with AppleScript in terms of functionality. See
 for more information and downloads.

The CALCore framework is private in OS X 10.4, so the usual disclaimers
apply w.r.t. using that. See 
for a basic example of use. Scuttlebutt says there'll be a public iCal
framework in 10.5, although that won't help the OP right now unless
they're a paid-up ADC member.

Windows Authetication vs seperate process

[imageguy1206]

I was wondering of someone could steer me in the right direction.

We have a package that we would like to "secure" so that only specific
individuals can access specific portions of the application.  Our
wxPython application will revolve around updating a central database
with information submitted from the app.  We will eventually have a web
front end fo rsome aspects of the app.

With several packages I have seen options to "Use Windows
Authentication", which seems to mean that "If the user has
authenticated and signed onto Windows, then our application will use
their windows userid and we will just focus on the the tasks within our
application the user is authorized to perform"

Does anyone have any experience using this type of authentication
scheme ?

Any related tips or suggestions ?

I have found a few wikipedia entries, but they seem to be more related
to webpages, etc.

Thanks.

"A lack of understanding," he answered sheepishly.

There are attributes (ie, question._qtext) that I do want to be the
same for every instance and thus don't want the extra memory overhead
of storing it anew for each instance.

Using the "instance" reference as you guys suggested, I'm now storing
the instance-specific information that the descriptors validate by
cramming it into instance._foo. Works great now!

Thanks for the additional understanding. It's a lot to wrap one's head

When you are trying things out in the Python shell IDLE, _ is a 
shorthand way to use the last value printed by IDLE.

Thus when
s.replace(', ',',')
prints out
'hello,goodbye,boo'
_ refers to that value so the replace operation
_.replace(',',', ')

manipulates that value.

press 'Abort script' button you should call new_window.destroy(), pack_forget() 
the current button & pack() the 'run script' button

Personally I'd go one step further and regularise the whitespace around the 
commas completely (otherwise what if you have spaces before commas, or 
multiple spaces after them:

>>> s = "hello, goodbye ,  boo"
>>> print ', '.join(t.strip() for t in s.split(','))
hello, goodbye, boo

Strange error with getattr() function

[Hole]

Hi There!

I'm trying to use Zope and the product OpenFlow.

I got the following error while I was using the built-in function
getattr() to retrieve an OpenFlow object:

attribute name must be string


Actually, I surely pass a string as attribute name to getattr()

The code:

#following instruction returns me the string "WorkFlowTest"
openflow_id=container.aq_parent.id

if (hasattr(container,openflow_id):
#the interpreter enter in this block, so
#it's sure that container has an attribute called WorkFlowTest
openflow=getattr(container,openflow_id)

At this point, I got the error: attribute name must be string

The *strange* is that I get the same error even if I pass the attribute
name to the getattr() function as pure string:

getattr(container,"WorkFlowTest")

(sic!)

I'm a lot confused!
Thanks in advance.

Run

  gdb python

Then type

  run msgppscomp.py

at the gdb prompt.

When it crashes, type "bt" for a back trace.  This will pinpoint
exactly where it crashes.

Hopefully that will make things clearer.  If not post the output.

You can do it with a zero width negative lookahead assertion, eg

  >>> import re
  >>> s="One, Two,Three,Four, File"
  >>> re.sub(r",(?!\s)", ", ", s)
  'One, Two, Three, Four, File'
  >>> 

>From the help :-

  (?!...)
  Matches if ... doesn't match next. This is a negative lookahead
  assertion. For example, Isaac (?!Asimov) will match 'Isaac ' only if
  it's not followed by 'Asimov'

Or in a more straightforward but less efficient and accurate style -
this matches the next character which gets added back into the string.

  >>> re.sub(r",([^\s])", r", \1", s)
  'One, Two, Three, Four, File'
  >>> 

This shows a fundamental difference between the two methods

  >>> t = ","
  >>> re.sub(r",(?!\s)", ", ", t)
  ', , , , , '
  >>> re.sub(r",([^\s])", r", \1", t)
  ', ,, ,,'
  >>>

Thank you for ALL for help.
Hendrik,
your solution works great but
what is `_`  in

for?
Thank you

Actually, this could just mean that on Windows, there is no suitable
implementation of the stdlib function time.sleep, and so attempts to
use it will result in bad behavior of some sort.

It does not necessarily mean that ShedSkin is doing anything which
might prevent the attribute `sleep' from being rebound on a module
importable as `time' to some other function which behaves differently.

Of course, what is not necessarily the case may still be the case. ;)

From the ShedSkin README:

Do not use:
  ...
  -reflection (getattr, hasattr), eval, or other really dynamic stuff
  ...

I would say that the example you presented above falls into the "really
dynamic stuff" category. ;)

And in fact, attempting to compile a program somewhat like the one above
results in this:

[EMAIL PROTECTED]:~/Scratch/Source/shedskin-0.0.16$ make
g++ -O3  -I./lib ./lib/builtin.cpp ./lib/time.cpp foo.cpp -lgc  -o foo
foo.cpp: In function ‘int __foo__::__main()’:
foo.cpp:6: error: assignment of function ‘void __time__::sleep(double)’
foo.cpp:6: error: cannot convert ‘unsigned int ()(unsigned int)’ to ‘void 
()(double)’ in assignment
make: *** [foo] Error 1
[EMAIL PROTECTED]:~/Scratch/Source/shedskin-0.0.16$ 

So yes, it seems that what ShedSkin supports is pretty distant from what
a seasoned Python developer might expect, aside from syntactic constructs.

Shed Skin - Does it break any Python assumptions?

[skip]

I just noticed the announcement of Shed Skin 0.0.16 on Freshmeat with this
(partial) change announcement:

Changes: frozenset was added. time.sleep now works on Win32.

Given Python's highly dynamic nature it's unclear to me how Shed Skin could
know enough about the semantics of time.sleep to know whether or not it's
broken on Win32.  This suggests that to gain speedups it probably implements
a more static language than Python.  For example, does Shed Skin handle a
case like this?

>>> import time
>>> time.sleep(1)
>>> def _sleep(n):
...   print "sleeping for", n, "seconds"
...   time._sleep(n)
...
>>> time._sleep = time.sleep
>>> time.sleep = _sleep
>>> time.sleep(1)
sleeping for 1 seconds

What does this phrase in the announcement mean?  "... pure but implicitly
statically typed Python ...".  Where does the static typing begin and end?
Can one module tweak another module's attributes?  Can a class's attributes
be modified from outside the class?  What about the attributes of a class
instance?

Yeah, you're right! I've already found that stupid error. I've entagled

Use the configure method to change the command of the button,
to point away from "run" to "abort", as the first thing done in "run".

You can change the text too to read correctly, at the same time, 
as well as the background colour to red...
