Python compiled on Windows

[Franz Steinhaeusler]

Hello, I'm only curious.

Why is Python and most extension (also wxPython) not built using an
open source compiler like gcc or g++ on Windows?

I'm always wondering, why Microsoft is still supported 
in that way, using VC++ 7.1, if I'm not wrong.

Ok, maybe the compiled assembler code could be better, but
this cannot be the reason, or?

It would be wonderful (from the principle) if this could be possible.

subprocess stdin encoding

[yc]

I have a encoding problem during using of subprocess. The input is a
string with UTF-8 encoding.

the code is:

tokenize =
subprocess.Popen(tok_command,stdin=subprocess.PIPE,stdout=subprocess.PIPE,close_fds=True,shell=True)

(tokenized_text,errs) = tokenize.communicate(t)

the error is:
  File "/usr/local/python/lib/python2.5/subprocess.py", line 651, in
communicate
return self._communicate(input)
  File "/usr/local/python/lib/python2.5/subprocess.py", line 1115, in
_communicate
bytes_written = os.write(self.stdin.fileno(), input[:512])
UnicodeEncodeError: 'ascii' codec can't encode character u'\xa9' in
position 204: ordinal not in range(128)


How I change the default encoding from "ascii" to "utf-8"?

Hi,

I had a similar problem recently and did not have time to file a 
bug-report. Thanks for doing that.

The problem is the code that handles entity and character references in 
SGMLParser.parse_starttag. Seems that it is not careful about 
unicode/str issues.

My quick'n'dirty workaround was to remove the offending char-entity from 
the website before feeding it to Beautifulsoup::

   text = text.replace('®', '') # remove rights reserved sign entity

cheers,
stefan

Is your MyCom object also in Python?  The only way this can happen is if
you are generating different GUIDs every time you register the thing.  If
so, you need to unregister the old version before you register a new one.

"Don't do that, then."

More specifically, 'from foo import *' is deprecated for exactly the
reason you found here: you risk clobbering an existing name in the
current namespace, and there's no way to determine that by looking at
the code.

Instead, import modules preserving a module namespace, which is the
behaviour you get from 'import foo'. That way, all names remain
explicit and you can see where you might be re-binding an existing
name.

>>> import random
>>> random

>>> import numpy
>>> random

>>> numpy.random


Alternatively, if you want *specific* attributes from a module or
package to be in the current namespace, import them explicitly by
name; the same applied above, that you can see which names in
particular are being re-bound.

>>> import random
>>> random

>>> from numpy import random
>>> random


Again: don't use 'from foo import *', without knowing exactly why
you're doing it. 'import foo' or 'from foo import bar' are always
available, and usually better.

numpy has a subpackage called random. You imported it when you did "from numpy
import *".

problems loading modules

[Frank]

Hi,

I have the following weird behavior when I load modules:


>>> import random
>>> print random.randrange(10)
8
>>>

Everything is fine.

>>> import random
>>> from numpy import *
>>>
>>> print random.randrange(10)
Traceback (most recent call last):
 File "", line 1, in ?
AttributeError: 'module' object has no attribute 'randrange'
>>>

Here it does not work.


>>> from numpy import *
>>> import random
>>>
>>> print random.randrange(10)
8
>>>

Now everything is back to normal.

That means the order the modules are loaded matters! I would expect
there is a problem with my installation because I guess this should
normally be independent of the loaded modules.

Here are my questions:
1. Does anyone has this behavior too?

2. How can I fix this problem?

I use linux with fedora core 6 and python 2.4.4

I appreciate any hint. Thanks!

There are 2 major updates regarding Parallel Python: http://
www.parallelpython.com

1) Now (since version 1.2) parallel python software could be used for
cluster-wide parallelization (or even Internet-wide). It's also
renamed accordingly: pp (module is backward compatible with ppsmp)

2) Parallel Python became open source (under BSD license): http://

Re: Recursive zipping of Directories in Windows

[Josh Bloom]

Hi Jandre,

Your code is treating the directory as a file and trying to open it and read
its bytes to zip them. You'll need to differentiate between files and
directories.

You'll need to check out the Zip module to see how it expects files that
should be nested within folders. I believe you'll need to set the archive
name for the nested files to something like \\temp\\file.ext etc.

Thank you Larry.
I've changed the code as epr your advice. The code is now:

import zipfile, os

def toZip( directory, zipFile ):
"""Sample for storing directory to a ZipFile"""
z = zipfile.ZipFile(
zipFile, 'w', compression=zipfile.ZIP_DEFLATED
)
def walker( zip, directory, files, root=directory ):
for f in files:
f = os.path.join( directory, f )
archiveName = os.path.basename(f)
zip.write( f, archiveName, zipfile.ZIP_DEFLATED )
print f
os.path.walk( directory, walker, z  )
z.close()
return zipFile


if __name__ == "__main__":
toZip( 'c:\\aaa\\', 'c:\\bbb\\test.zip' )

I still get the same error:
Traceback (most recent call last):
  File "C:\Python24\Lib\site-packages\pythonwin\pywin\framework
\scriptutils.py", line 310, in RunScript
exec codeObject in __main__.__dict__
  File "C:\Python24\Scripts\dirZip.py", line 20, in ?
toZip( 'c:\\aaa\\', 'c:\\bbb\\test.zip' )
  File "C:\Python24\Scripts\dirZip.py", line 14, in toZip
os.path.walk( directory, walker, z  )
  File "C:\Python24\lib\ntpath.py", line 329, in walk
func(arg, top, names)
  File "C:\Python24\Scripts\dirZip.py", line 12, in walker
zip.write( f, archiveName, zipfile.ZIP_DEFLATED )
  File "C:\Python24\lib\zipfile.py", line 405, in write
fp = open(filename, "rb")
IOError: [Errno 13] Permission denied: 'c:\\aaa\\temp'

c:\\aaa\\temp is a directory in the directory I an trying to zip. I
want to use this script to back up my work once a day and would like
to
keep the directory structure as is. I can zip the files in c:\aaa\tem
fine so I guess that there aren't any open files in the directory.
Any more ideas?

There is no "right way" to handle the issue of initialising attributes.
The above way is very common, easy, self-documenting and doesn't have that
many disadvantages unless you have lots of parameters to deal with.

That's even worse.

Which is correct?

Stats(..., armour, stealth, ...)
Stats(..., stealth, armour, ...)

You have to read the code to find out. Not just the function definition,
but you actually have to read through all the assignments. Bad bad bad.

def __init__(self, **kwargs):
for key in kwargs:
if hasattr(self, key):
# key clashes with an existing method or attribute
raise ValueError("Attribute clash for '%s'" % key)
self.__dict__.update(kwargs)


=== Advantages ===

(1) you can create new attributes without changing any code;
(2) creating an instance is self-documenting:

Stats(armour="chainmail", stealth=2, strength=4, ...)

(3) attributes can be added in any order;
(4) easy to modify the class so it inherits sensible defaults:

class Stats:
armour = "leather"
wisdom = 10
dexterity = 10
weapon = "sword"
def __init__(self, **kwargs):
for key in kwargs:
if self.__dict__.has_key(key):
raise ValueError("Attribute clash for '%s'" % key
self.__dict__.update(kwargs)



=== Disadvantages ===

(1) You have to put in the attribute name, always:

Stats(armour="chainmail", stealth=2, strength=4, ...) instead of
Stats("chainmail", 2, 4, ...)

(2) Typos can cause strange bugs which are hard to find:

Stats(armour="chainmail", stealth=2, stregnth=4, ...)

Now your character is unexpectedly strong because it inherits the default,
and you don't know why.

(3) Easy to break your class functionality:

Stats(name_that_clashes_with_a_method="something else", ...)



If you've got lots of attributes, you're better off moving them to
something like a INI file and reading from that:

class Stats:
defaults = "C:/path/defaults.ini"
def __init__(self, filename=None, **kwargs):
if not filename:
filename = self.__class__.defaults
self.get_defaults(filename) # an exercise for the reader
for key in kwargs:
if not self.__dict__.has_key(key):
raise ValueError("Unknown attribute '%s' given" % key)
self.__dict__.update(kwargs)

Notice that here I've changed from testing for attributes which clash to
testing for attributes which *don't* match a key in the INI file. Which is
the "best" behaviour, I leave up to you to decide.

Here's a suggestion: use new-style classes.  Have _BaseEntity inherit
from object, allows you to use super for invoking methods on super
classes.  Instead of:
class Entity(_BaseEntity):
def __init__(self, type, x = 0, y = 0):
_BaseEntity.__init__(self, type, x, y)

You enter:
class Entity(_BaseEntity):
def __init__(self, type, x = 0, y = 0):
super(Entity,self).__init__(type, x, y)

This makes it easier to update your inheritance hierarchy later.  New-
style classes have other benefits too.

As for your NoneType problem, try adding "print self._direction" to
the end of _BaseElement.__init__.

sgmllib bug in Python 2.5, works in 2.4.

[John Nagle]

(Was prevously posted as a followup to something else by accident.)

I'm running a website page through BeautifulSoup.  It parses OK
with Python 2.4, but Python 2.5 fails with an exception:

  The code that's failing is in "_convert_ref", which is new in Python 2.5.
That function wasn't present in 2.4.  I think the code is trying to
handle single quotes inside of double quotes, or something like that.

Return images with matplotlib?

[Jan Danielsson]

Hello all,

   I have written a program which takes some data from a postgresql
database, and via mod_python outputs it as tables on a web site. Now I
would like to present these tables as graphs, which matplotlib can do.
  But in order to properly display these graphs on the web page, I need
to return the image data, like so:

def barchart(req, params):
   some_format = matplotlib.generate_fancy_graph(params)
   png_buf = make_png_buffer(some_format)
   return png_buf

   Is this possible? If so -- how?

That is not true if 'prefork' MPM is used for Apache which is how most
people seem to run it. This is because each Apache child process only
run one request at a time and so there isn't normally going to be any
contention on the GIL at all. The only case where there would be
contention in this arrangement is if the request handlers within
Apache had spawned off distinct threads themselves to do stuff. Even
then, in this arrangement the main request handler is usually not
doing anything and is just waiting for the created thread to finish
what it was doing. Thus if only one thread was spawned to do some work
or a blocking operation to allow the main thread to timeout, then
again there isn't really any contention as only one thread is actually
doing anything. If you are trying to embed very intensive operations
with threads within Apache then I would suggest it is not really the
best design you could use anyway as such things would be much better
farmed off to a long running backend process using XML-RPC or some
other interprocess communication mechanism.

If one is using the "worker" MPM then yes there will be some
contention if multiple requests are being handled by mod_python at the
same time within the same Apache child process. The downside of this
is lessened however by the fact that there are still multiple Apache
child processes and Apache will spread requests across all the Apache
child processes, thus the amount that may be running concurrently
within any one process is less.

The basic problem of GIL contention here is no different to a single
Python backend process which is handling everything behind Apache. In
some respects the Apache approach actually works better as there are
multiple processes spreading the load. Your comment on the GIL is
therefore partly unjustified in that respect for Apache and
mod_python. Your statement in some respect still stands for Python
itself when run as a single process, but you linked it to mod_python
and Apache which lessens the impact through its architecture of using
multiple child processes.

Finally we have 'winnt' MPM, again, because this is all in the one
process you will have GIL contention in a much more substantial
manner. However, I'd suggest that most wouldn't choose Apache on
Windows as a major deployment platform.

How is that any different to Apache child processes. Each Apache child
process has a full copy of Python and the libraries in use. Each
Apache child process can be making use of different CPUs. Further,
static file requests, plus other requests against PHP, mod_perl etc
can when mod_python is also running be on separate CPUs within the
same child process when 'worker' MPM is being used. Thus you haven't
lost all forms or parallelism that may be possible, it is only within
the mod_python world that there will be some GIL contention and only
with 'worker' and 'winnt' MPMs, not 'prefork'. It isn't going to lock
out non Python stuff from making use of additional CPUs.

Re: when will python 2.5 take in mainstream?

[[EMAIL PROTECTED]]

When they have to ...

One of the big things about Python is that its penetration slows it
down. There's more legacy code and interdependant systems around now
that Python is more successful and more mature.

Here's a thought -- perhaps it would be worth having some good ways to
interact with Python from Python. Suppose you have some 2.4 code
someplace, interacting with your mysqldb or whatever, and you don't
want to rewrite it. So long as you have some kind of object broker,
you could (plausibly) leave your 2.4 apps running with the old
interpreter, but wrap them for Python 2.5 and use that in your new
development.

Ditto 3.0.

Rather than having to re-write every interacting component, maybe it
could be straightforward to all Python2.4 from Python2.5 to execute
particular library calls. I'm not an expert, I don't know how you'd
build such a system, but I do know that re-writing stuff is a real
pain.

Perhaps APIs for 2.5 and 3.0 could have a special version flag, and if
not present or not compatible, a 2.4 interpreter could be called
instead...

Cheers,

Line 15 is:
self.pos += (self._direction * self.stats.speed)
So obviously(???) self._direction is None

What does line 8 do: self._direction = vector() ???

I'd suggest adding line 8.1:

assert self._direction is not None

 Realistically, mod_python is a dead end for large servers,
because Python isn't really multi-threaded.  The Global Python
Lock means that a multi-core CPU won't help performance.

 FastCGI, though, can get all the CPUs going.  It takes more
memory, though, since each instance has a full copy of Python
and all the libraries in use.

 (FastCGI is a straightforward transaction processing engine.
Each transaction program is launched in a separate process, and,
once done with one transaction, can be used to do another one
without reloading.  When things are slow, the extra transaction processes
are told to exit; when load picks up, more of them are forked.
Security is comparable to CGI.)

I had a more complete response to this before Google Groups and my
browser went into "stupid mode" together, but I'd like to say that I
don't have any complaints about mod_python, but I know that there were
people who claimed [1] that PHP had its "safe mode" [2] which gave
isolation to applications belonging to different users in the same
Apache instance, asserting that mod_python not having that particular
feature prevented wider adoption of Python in the hosting business.

It's good to see a clarification of mod_python and its position in
relation to such issues, though. I don't really share the concerns
mentioned, and wouldn't want to be using or providing services of the
kind previously discussed, anyway. Instead, I'd want to deploy
applications using other techniques such as virtualisation, rather
than throwing customers into the same Web server and, apparently in
the case of PHP, relying on hearsay about whether they can interfere
with each other. I note that the creator of mod_python seems to have a
similar perspective on virtualisation, given the nature of his hosting
company's services.

To clarify some points about mod_python, since these posts do not
properly explain the reality of the situation and I feel people are
getting the wrong impression.

First off, when using mod_python it is possible to have it create
multiple sub interpreters within each Apache child process. These
distinct sub interpreters can be linked to different parts of the URL
namespace. This means that it is possible to host more than one
mod_python application where each executes within in their own
distinct sub interpreter. The outcome of this is that each application
can have their own sys.path, own os.environ, own sets of modules and
potentially with different versions of some module.

Maintaining separation using sub interpreters eliminates the bulk of
problems with applications interfering which each other at least
within a process. Some problems can still arise though where third
party extension modules for Python aren't written so as to be usable
from multiple sub interpreters at the same time however. This is not a
failing of mod_python though, but a failing of the module writers.

The main area where interference can occur is where applications needs
to write to the file system. This is because all code will be
executing as the user that Apache runs as. Thus, distinct applications
could overwrite each others data within the file system. On one level
this just means that applications need to be configured to always use
their own part of the file system. For example, if using the support
in mod_python for sessions, the distinct applications should perhaps
use separate session databases rather than use the same common
database. Ultimately though, a rogue application could write where
ever it wants to, but from what I know (and could be wrong), this
isn't different to other languages systems within Apache such as PHP
and mod_perl.

Another possibility for interference is where an application simply
does something bad like get stuck in a tight loop or consume lots of
memory. Such an event can possibly interfere with other applications,
even across language boundaries, however, how bad the impact will be
depend on what MPM is used by Apache.

If "prefork" MPM is used, then the request being handled by that
application is the only thing which would be running within that child
process at that particular time. Thus, if it stops the functioning of
just that one process it doesn't matter as Apache will just farm
requests off to other child processes. If that initial child process
crashes because of the problem, then again it doesn't matter as Apache
will just create another child process to replace it and will
otherwise keep running.

If the "worker" MPM is used the impact can be greater as there could
be other requests being handled concurrently within the same child
process and the performance of those requests may be hindered. If the
worst happens and the child process crashes, only other requests being
handled within that specific child process would be affected, those in
other child processes would again continue unaffected as would Apache
as a whole.

The worst case is the "winnt" MPM (ie., Windows boxes). This is
because there is only one Apache process and thus a rogue application
can affect the whole Apache web server.

It should be highlighted though that this class of problem is not
unique to Python or mod_python as you could get rogue code in a PHP
page or mod_perl application just as easily.

What it all really comes down to is that the only features that are
really missing are the ability for distinct applications to run as
distinct users, or for applications to run inside of some sort of
chroot environment. Some aspects of this are addressed by FCGI and
SCGI, but again lack of this feature within mod_python itself is not
unique to it and that as far as I know is also going to be an issue
for other language systems for Apache such as PHP or mod_perl.

Having said all that, perhaps those who are complaining about lack of
support for specific features in mod_python can now clarify what
actually you are talking about. At the moment the brief comments being
made seem to possi

Excellent comment by the internet spook on duty. Your analysis is
correct that they are CIA PATSIES. They dont have the smarts of Cuba,
India, Iran, Venezuela, Israel or the Yanks. Its quite obvious who is
behind the controlled demolition of Silverstein Properties and the
Golden Dome of that mosque or shrine of the Shia.

Dr Fidel Castro Ruz has made Cuba into a leading Biotechnology Center
of the World. Many American sheeple dont even know the full name of Dr
Ruz, or his occupation or even the status of Cuba as the leading
Biotechnology Center in the world.



RESPONSE FROM DR. FIDEL CASTRO RUZ, PRESIDENT OF THE REPUBLIC OF CUBA,
TO THE STATEMENTS MADE BY THE UNITED STATES GOVERNMENT ON BIOLOGICAL
WEAPONS.

Hardly three days ago, someone only too well known to us, Assistant
Secretary of State Otto Reich was caught out in an embarrassing lie
when he said that four Cuban planes had landed in the Venezuelan
capital on April 12, and that nobody knew "what they were doing there,
what they were carrying, we don't know". Apparently, it was the
beginning of an anti-Cuba campaign or a vendetta due to the amazing
failure of the fascist coup he set in motion, or both.

On Tuesday May 7, when the Ministry of Foreign Affairs challenged him
publicly, the State Department said that it had no confirmation
whatsoever, and that it did not want to discuss the subject any more.

The idea of destroying Cuba, an obsession that has lasted more than 43
years, has lead and still leads U.S. policy down a tortuous path
filled with lies, mistakes, failures and crimes. What the US
government is telling the world today and what it is doing with Cuba
is perhaps the most grievous and demoralizing contradiction in its
foreign policy. This great power had never found itself in such a
compromising position and it has no alternative but to lie, lie and
lie. And there is no lack of unscrupulous characters in major public
positions willing to do so, no lack of press spokesmen caught up in
the continuous and bitter need to right wrongs and explain the
inexplicable in their bosses' statements.

Even men like Colin Powell, son of Jamaican immigrants, that despite
his military training or maybe because of it, is not considered a hawk
since he knows about war and has seen many men die --a man that many
Americans even came to look on as a potential presidential candidate--
has found himself enmeshed in shameful and little ennobling intrigues
promoted by such characters. He knows better than anyone else how
inexperienced they are and what little intellectual and political
worth those people have.

Whom this new character involved in a sinister maneuver against Cuba
can deceive? Mr. John Bolton, an Under Secretary of State, none other
than the one for Arms Control. What are they aiming for with the
attack launched by this official in an aggressive speech against Cuba
given at the Heritage Foundation, famous for its ultra-rightwing
stance?

His statement, supposedly an analysis of the dangers of terrorism
threatening the United States, begin by saying: "In addition to Libya
and Syria, there is a threat coming from another BWC signatory, and
one that lies just 90 miles from the U.S. mainland-namely, Cuba."

Then, after the usual name-calling and stupid remarks full of the
hatred common in such arrogant and misinformed people, Mr. Bolton
added something all his own:

"We know that Cuba is collaborating with other state sponsors of
terror."

"Castro has repeatedly denounced the U.S. war on terrorism. He
continues to view terror as a legitimate tactic to further
revolutionary objectives. Last year, Castro visited Iran, Syria and
Libya --all designees on the same list of terrorist-sponsoring states.
At Teheran University, these were his words: 'Iran and Cuba, in
cooperation with each other, can bring America to its knees. The U.S.
regime is very weak, and we are witnessing this weakness from close-
up.'"

"But Cuba's threat to our security has often been underplayed. An
official U.S. government report in 1998 concluded that Cuba did not
represent a significant military threat to the United States or the
region. It went only so far as to say that, 'Cuba has a limited
capacity to engage in some military and intelligence activities which
could pose a danger to U.S. citizens in some circumstances.'"

Mr. Bolton immediately looked for something to cover up the suspicious
fact that it had never before occurred to any US government official
to make such an infamous accusation against Cuba. Mr. Bolton blames
this weaknes

You discovered wrong -- Google does not provide a free newsserver. They no

either free, or for a fee. They only provide a web interface to access the

You're of course right. Exceptions are mainly a way of handling 
'exceptional' conditions without cluttering the source code with error 
code checking. The canonical use case is:

try:
   some_call_that_may_raise(args)
except SomeException, e:
   try_to_solve_the_problem()

The nice thing with exceptions (compared to 'manual' error handling) is 
that you can choose where you want to handle the problem without having 
to pass back error code/error message all along the call stack...

IDE stands for "Integrated Development Environment". Since one of the 
central tasks in development is editing code, IDEs are usually built 
around the editor.

Just a note, If you run the module from different location, it may not always 
work.

The '..' is relative to the location you are running the module from, the 
current directory, and not relative to the location of the module is at.

It won't be a problem for you if you can be sure the module is always ran from 
the location it is at.

I think that the integration of certain "popular" extensions into the
Python distribution has been one of the tools employed to mitigate the
version compatibility situation: if the popular stuff gets released
with Python, perhaps fewer people will complain about "C modules"
whose developers/maintainers haven't updated them for the latest
release. I'm not really convinced that this makes for a sustainable
approach, however, since this just becomes a process of accretion
where the core development community must get larger and become very
well-coordinated in order to manage the dependencies within the
software, as well as tracking external dependencies.

Over the years there have been suggestions which might have made the
compatibility situation a bit better: a "Python in a tie" release was
an objective of the seemingly dormant Python Business Foundation;
Linux Standard Base inclusion of Python has been proposed and
discussed. I can't help feeling that without improvements in such
other areas, things like "C module" availability for different Python
versions (and for different versions of related libraries) is mainly
an issue of doing the almost thankless hard work of backporting,
testing and managing different build configurations. Still, there may
be demand for a backports community in all this.

not. But then I discovered that Google has a free newsserver, so I
joined this group from there. Sadly, I cant see a feature here that

It is good to blow up a marketplace full of people buying and selling food

[Frank Arthur]

It is good to blow up a marketplace full of people buying and selling food
in Iraq.
This is how Muslim insurgents will drive "the enemy" out of their country.
By killing and maiming fellow Iraqis! The traditional Muslim way.
The way of Allah! The way of the Quaran! The way of Mohammed!
They don't need any democracy. They don't need free elections. They are true
believers!

Suicide truck bomber kills at least 130 in Baghdad
By Tina Susman, Times Staff Writer
11:23 AM PST, February 3, 2007


BAGHDAD -- A suicide bomber posing as a trucker hauling food drove into a
busy market in central Baghdad today and blew himself up, killing at least
130 people, injuring more than 300, and capping a particularly volatile day
in Iraq's sectarian war.

Seven car bombs also tore through the northern city of Kirkuk, leaving two
dead in attacks that underscored tensions enveloping the oil-rich region as
Arabs and Kurds vie for power. Another person died south of Baghdad in a
separate car bombing.


The incidents illustrated the breadth of polarization plaguing Iraq as U.S.
and Iraqi officials prepare for what they vow will be a decisive crackdown
on insurgents.

The Interior Ministry said the blast in the market in Sadriya killed at
least 130 people and injured 305. It came in the early evening as shoppers
thronged the stalls and tiny shops to stock up for the evening meal. Hamed
Majed, a butcher, was tending to customers when he saw a large yellow truck
trying to navigate down the narrow, alley-like street leading through the
market.

Thank you Larry.
I've changed the code as epr your advice. The code is now:

import zipfile, os

def toZip( directory, zipFile ):
"""Sample for storing directory to a ZipFile"""
z = zipfile.ZipFile(
zipFile, 'w', compression=zipfile.ZIP_DEFLATED
)
def walker( zip, directory, files, root=directory ):
for f in files:
f = os.path.join( directory, f )
archiveName = os.path.basename(f)
zip.write( f, archiveName, zipfile.ZIP_DEFLATED )
print f
os.path.walk( directory, walker, z  )
z.close()
return zipFile


if __name__ == "__main__":
toZip( 'c:\\aaa\\', 'c:\\bbb\\test.zip' )

I still get the same error:
Traceback (most recent call last):
  File "C:\Python24\Lib\site-packages\pythonwin\pywin\framework
\scriptutils.py", line 310, in RunScript
exec codeObject in __main__.__dict__

c:\\aaa\\temp is a directory in the directory I an trying to zip. I
want to use this script to back up my work once a day and would like
to

 The real problems are with integration of modules that
aren't written in Python.  Python-only modules don't have the
version compatibility problems which C modules do.  Loading
a Python-only module from an external source is usually not
a big deal.  Building a C module, especially one with
dependencies on other components, can be a big deal.
So, focus on problems with modules which have C
components.

As I understand it, the effort is directed towards elaborating the

This would be a good step but numpy os much more and is of minority

Python core.

Using keyword arguments instead of positional parameters makes this easy:

[ANN] ConfigObj 4.4.0 and Validate 0.2.3

[Fuzzyman]

Updated versions of both `ConfigObj `_ and `Validate `_ are now available.

* `ConfigObj 4.4.0 `_
* `Validate 0.2.3 `_

**ConfigObj** is a Python module for the simple reading and writing of
config files. It has many features, whilst remaining easy to use.

With the assistance of **Validate** it can validate a config file
against a specification, and convert members to the expected type.

Thanks to Nicola Larosa who implemented most of the fixes in this
release.


What is New in ConfigObj 4.4.0?
===

* Made the import of compiler conditional so that ConfigObj can be
used with IronPython.

* Fix for Python 2.5 compatibilities.

* String interpolation will now check the current section before
checking DEFAULT sections. Based on a patch by Robin Munn.

* Added Template-style interpolation, with tests, based on a patch by
Robin Munn.

* Allowed arbitrary indentation in the ``indent_type`` parameter.

* Fixed Sourceforge bug #1523975 by adding the missing ``self``


What is New in Validate 0.2.3?
==

Fixed validate doc to talk of boolean instead of bool; changed the
``is_bool`` function to ``is_boolean`` (Sourceforge bug #1531525).

Open house at Iranian nuclear site

Isfahan, Iran
February 5, 2007
AdvertisementAdvertisement

Iran has opened one of its nuclear sites to local and international
reporters and ambassadors to show the transparency of its program
before a UN Security Council deadline this month.

Tehran has kept up efforts to give the site at Isfahan more publicity.
A tourism official said late last year that Iran planned to open it
and other nuclear plants to foreign tourists.

Iran's ambassador to the International Atomic Energy Agency, Ali
Asghar Soltanieh, said the purpose of the tour was to assure the world
that Iran's program was peaceful.

"In fact we have representatives from all over the world," Mr
Soltanieh said. "We decided to have them come here and see for
themselves," he said.

He made a point of emphasising the IAEA surveillance cameras at
Isfahan.

Photographers and video camera operators were not allowed to take
pictures in the outside area of the compound.

Uranium ore is converted into yellowcake and gas at Isfahan. The gas
is transferred to the more sophisticated plant at Natanz, where it
could be enriched with centrifuges.

Reporters at the weekend passed the Natanz site but were not allowed
inside, where Iran recently said it was installing 3000 centrifuges.

Except that if a full regex is used, the pattern can be matched or
denied and pull out the important information simultaneously. Here's a
simple regex that would work:

(\d{1,2}):(\d{1,2}):(\d{1,2})

but here's one that works only for the 12 hour clock:

((1[012])|(0?\d)):([0-5]?\d):([0-5]?\d)

and one for the 24 hour clock:

((2[0-4])|([01]?\d)):([0-5]?\d):([0-5]?\d)

I hope this helps

I often use something like this, based on a Martellibot posting:

>>> class Stats(dict):
... def __init__(self, *args, **kwds):

... self.update(kwds)
... def __setitem__(self, key, value):

Because Python is just another thing to support for various hosting
providers. One of the problems people supposedly have when persuading
such companies to add or update packages is, I imagine, a lack of
familiarity those companies have with Python technologies. Asking them
to use a technology-specific packaging system might be a bit much if
they aren't even familiar with (or interesting in knowing more about)
the packages required to satisfy their customers' basic needs.

Moreover, there's a lot of software in the average GNU/Linux or BSD
distribution, but if you had to "break out" into technology-specific
package/dependency managers to install some of the more heterogeneous
packages, it would be a nightmare: perhaps installing the
documentation would have you visit CPAN for some Perl scripts before
throwing you into the TeX package manager to get some missing TeX
libraries; then you might be off into setuptools for the Python
scripting extensions, possibly via equivalent tools for other
scripting extensions; finally, you'd be off via any other system
thought essential to manage software from a particular parochial
technological viewpoint. I've had to install software like this, and
it takes huge amounts of time for no good reason if you can use system
packages instead.

You may use something like this:

def selfassign(self, locals):
# Code from web.py  http://webpy.org  modified.
for key, value in locals.iteritems():
if key != 'self':
setattr(self, key, value)

Generally used in __init__ methods, as:

def __init__(self, foo, bar, baz=1):
selfassign(self, locals())

You may use it as (untested):

class Stats:
def __init__(self, speed, maxHp, armor, strength, attackSpeed,
imagePath):
selfassign(self, locals())
self.originalImage = loadTexture(imagePath)
del self.imagePath

I don't like that del

would need to add it in three places. Add it to the function
parameters, add it to the class and assign it.

Is there a smoother way to do this? There usually is in python, hehe.
I recall when reading python tutorials that you could do something
like this:

foo(*list_of_parameters):

To send many parameters as a list or a tuple. Then I could assign them
like this:

You can add attributes and methods to old-style classes.

Are you sure you're using the word "classes" correctly? That seems ...
strange. I'm wondering whether the properties are class _instances_.

Okay, let me see that I understand what happens. Here's some pseudo-code
of what I think you are currently doing:


oref = get_a_reference_to_Cache_database()  # or whatever
# now do work on it using the python bindings.
oref.set("Name", "Peter")
oref.set("Something", "Else")


Here's a wrapper for the bindings, so they work more pythonically:

class Oref_Wrapper(object):
def __init__(self, oref):
self._oref = oref  # save the oref for later use
# Delegate attribute access to the oref
def __setattr__(self, name, value):
return self._oref.set(name, value)
def __getattr__(self, name):
return self._oref.get(name)  # or whatever the oref does
def __delattr__(self, name):
return self._oref.del(name)  # or whatever the oref does


This is how you use it:


oref = get_a_reference_to_Cache_database()  # or whatever
# re-bind the name to a wrapped version
oref = Oref_Wrapper(oref)
# now do work on it
oref.Name = "Peter"
oref.Something = "Else"

Do you use insCacheClass and insCacheProperty for anything other than
making the bindings more Pythonic? Because for the life of me I can't work
out what they're supposed to do!

Using my code above, oref.METHODNAME(args) would resolve to:

oref._oref.get("METHODNAME")(args)

which may not do what you want. 

If you know all the possible METHODNAMES, then that's easy enough to fix:
create methods at runtime. (If you don't know the methods, the problem
becomes too hard for me to work out at 3am, but will probably still be
solvable.)

Change the __init__ method above to something like this (untested):

import new

class Oref_Wrapper(object):
def __init__(self, oref):
self._oref = oref  # save the oref for later use
METHODNAMES = ["Save", "Clear", "Something"]
for name in METHODNAMES:
function = lambda self, *args: \
self._oref.run_obj_method("%"+name, args)
method = new.instancemethod(function, name)
self.__dict__[name] = method

then define the __getattr__ etc. methods as before, and (hopefully!) you
are done:

oref.Save()
oref.Clear(1, 2, 3, 7)



I hope this was of some help.

In fact, it is quite frustrating to operate under the impression that
"Python is good for X, Y, Z, " and then realize "ooops, it is
becoming a pain in the ass to do X, whereas language L does X just
fine". It seems to me that Python advocates sometimes (often?) get
carried away. DB "sure, no problem"; web-frameworks "who needs Rails,
we have (lots of) frameworks that do it"; functional programming
"Python can do all the functional programming anyone in his/her mind
should ever try to do"; etc.

Compare this to the, in my opinion, equanimous, fair, "advertisement"
one finds in the Erlang page or the recognition by schemers that
scheme is not the only game in town.

I would define an IDE as a system that supports multiple tasks of 
the development process using a related set of interfaces.  Some of 
these tasks may include:

Searching and browsing reference documentation.
Writing source code.
Building/compiling projects. 
Evaluation using a shell or REPL.
Debugging and testing.
Production of graphical elements.
Production of documentation.
Packaging.
Project management and version tracking.

I'll agree that it's a spectrum with the most comprehensive IDEs 
supporting more different tasks of the development process.

The other problem is that it chains the python release schedule to 
that of MySQL AB (and postgresql, and whatever.)  One of the key 
advantages to independent modules is that I don't need to update my 
entire python system every time my database vendor releases a new 
library, nor do I have to accept lag time as the module is tested 
and rolled into the base distribution.  Database client libraries 
are much more of a moving target than core language features.

I find it interesting that PHP struggled with these issues and 
decided to abandon embedded MySQL support partly because they 
couldn't maintain their own parallel versions of the client 
libraries.
  
http://us2.php.net/manual/en/faq.databases.php#faq.databases.mysql.ph
p5

Among the other problems faced by both PHP and Python in bundling 
MySQL support is that they can't legally do it without adopting the 
GPL.  

Which leaves me wondering why the python core should adopt a feature 
that was abandoned by PHP, and was never highly recommended or used?

And why eggs wouldn't satisfy them?  Eggs can be installed globally as well,
making the package available to every client of this hosting server (if they

I was really advocating improvements to the built-in SSL support,
anyway, which was also what the complainant was suggesting before
people started asking him mistakenly why he thought that Python was
weakened by some third party packages (PyOpenSSL, M2Crypto). The
choice here involves either improving the built-in support or
unbundling SSL-based communications altogether. The former option
obviously demands a certain amount of engineering, and then one might
ask why there isn't a convenient framework for plugging in other
flavours of sockets, for example, although there arguably aren't any
as generally important as secure sockets. The latter option needs
everyone to think about how you'd plug such stuff back into Python in
a nice enough way, and then to get people to work on the right
projects to provide something which does the job.

Really, we have to ask whether including the batteries would save
people a lot of work, not just in whether the end-user has to find out
about an external package and then download something, but whether the
logistics around developing the code, integrating it with Python, and
maintaining it would be easier if people just included the stuff with
Python. Here, you need some kind of consensus that feature X needs
supporting and there's an approved way of supporting it which a group
of people would be happy to maintain. Would it benefit the Python
community (including core developers) more if Python shipped with SSL
support out of the box, and would the cost of doing so ultimately be
less than just pointing people at third party libraries and dealing
with their problems?

>  We then get the question of whether to include any specific function and

Would it benefit the Python community more if Python shipped with
MySQL support out of the box? Is it likely that a user suddenly finds
him/herself needing to connect to a MySQL database? Is it more likely
that the user might suddenly find him/herself needing to download from
a secure site, particularly if some tool (eg. setuptools) suddenly
stumbles across an https URL. Some database systems have a choice of
drivers/libraries/modules (PostgreSQL has quite a few, for example):
choosing a module for standard library inclusion and integrating the
development can be too high a barrier for such questions of inclusion
to be resolved trivially.

On various distributions you get packages which don't actually contain
anything, but which indicate a suite of packages which are to be
installed. So, if you install the ubuntu-desktop package on Ubuntu
systems, you get the GNOME desktop environment and all the
dependencies (and a bunch of other stuff). Perhaps there should be a
python-mysql-hosting package for such providers.

And while Python eggs may be useful for people managing additional

It's was a hack and definitely not meant to go in to production ;)
Since gzip.py lives in python24\lib I thought setting sys.path[0] to

However, in some magically way the sys.path gets modified during the

causing sporadic problems when request are handled concurrently? I
just don't know. The iis/inetsrv path is included in sys.path for a
reason and I don't want to fiddle around with sys.path to create

way to prevent a  name clashes by using a custom importer or something

The best overall solution is the one where you modify sys.path to add
your own custom paths, however Jussi is right in that you do not need

Hmm - pywinauto is not supported on Windows 98 - it relies competely

You could try renaming all the functions ending in W to ending in A

fairly sure that this would NOT solve all the problems you would have
trying to run on W98.

As far as I know (not 100% sure) but ctypes should have no problem on

Another thing to look into might be Unicows.dll (which gives some

No, it doesn't. PYTHONPATH can be updated somewhere in the environment

Rob,
thank you very much,
that's exactly what I want.
(Why is the obvious so often invisible to me ;-)

Do you mean something like that?

>>> import some_module
Traceback (most recent call last):
  File "", line 1, in ?
ImportError: No module named some_module

For this kind of stuff, I'd try to put "self.out.WriteText(string)" in 
some 'Idle' event, which avoid to fall in focus loops or other objects 
events management problems not easy to solve.

Did you try something like that :

def write(self, string):
 self.outBuffer= string
def onIdle(self,event):
 if self.outBuffer != None:
 self.out.WriteText(self.outBuffer)
 self.outBuffer= None

Could you point to such documentation?  The search function in the online
docs doesn't know about "laptop".

There must be enough memory to display a full screen, obviously,
everything else is done in main memory then.  And you are talking about
panda3d functions and not pygame ones.  The OP wanted to write simple 2D
games, so it's irrelevant if panda3d doesn't work on some laptops. 
Claiming pygame doesn't work on about 50% of the laptops out there based
on these facts is a bit exaggerated.

When I have Excel stuff to do, I use :
http://sourceforge.net/projects/pyexcelerator
May be it can cover your needs ?
 From my point of view, COM is something to avoid : no docs, lot of 
investigations, weak results.

No of course not.  Java is very similar in only passing references around
for objects.  And `ArrayList` and `Vector` behave similar to Python lists.

For a start they don't have a built in list type.  C and Pascal don't even
have one in the standard library.  C++ has STL vectors and if you, the
programmer, decide to store pointers in it instead of structures or
objects then you have something like Python's list type.

Can't give definitions, but here is the difference: if you use an editor, you 
will have to run your script or program from outside the editor; if you use 
an IDE, you will press a key or key combination in the IDE (say F9 or F5) and 
your program/script will run...

Yes is exactly what i want to do... i don't known because i looked at
cookielib to set cookie data, cookie are simply http header :) Inserting
values with add_header() or addheaders() it works. Thank you
