Hallo,
I hope, that I interpret your question in the right way.
You can use the following function as a starting point to get all
files ending with py or pyc from your working dir.
Invoke getAllFilesOfPatterns(".","*.py *.pyc")

import os
import fnmatch
def getAllFilesOfPatterns( dir ,patterns="*",  recursive=True  ):
""" patterns must be space separeted string of patterns
e.g: *.pdf *.ps *.html
"""
patterns= patterns.split()
retValue=[]
for path,dirs,files in os.walk(dir):
for file in files:
for pattern in patterns:
if fnmatch.fnmatch( file , pattern ):
retValue.append(os.path.join(path,file))
if not recursive: break
return retValue

for it. Check it out. It's really good. Makes me want to start making videos

Re: Videocapture in python

[alex goretoy]

Can you post your code or a code segment? I would be interested in seeing
how this works.

Re: select.select and socket.setblocking

[Francesco Bochicchio]

Can you post an example program that exhibits the behavior you
describe?




I was forgetting about the MSG_WAITALL flag ...
When I started programming with sockets, it was on a platform (IIRC 
Solaris) that by default behaved like MSG_WAITALL was set by default
(actually, I don't remember it being mentioned at all in the man pages). 
This sort of biased my understanding of the matter. I actually used that
flag recently - on Linux - to get the same behavior I was used to, but 
forgot about that.


My bad :-)

Ciao

idle 3.0 unicode

[Pavel Kosina]

As for unicode in Python 2.5 everything works fine in program running 
either in IDLE or under Command line:

# -*- coding: utf-8 -*-
print u"ěščřžýáíé"

In 3.0 there is an error.  The same program, moved to 3.0 syntax, in 
IDLE editor :

# -*- coding: utf-8 -*-
print ("ěščřžýáíé")

prints:
ěščřžýáíé

The same program running in Command line from PSPad editor works fine.  
Is it mistake of my misunderstanding or of IDLE?


-

The same program without coding declaration (but saved in utf8) :
print ("ěščřžýáíé")

even immediately destroyed my IDLE window without any error message.

"Common" sense suggests that his views are shared among the general
populace. I don't see much evidence of that in the sometimes never-
ending threads that frequently follow his postings. But it is good to
start debates about making changes to the status quo, often the
debates will result in worthwhile changes, even if those changes are
not what he proposed. I just wish he would choose his venue a little
more carefully sometimes.
