it is not because it does work on an implementation of python

I forgot the most important, I am looking for a non recursive method.

how can I modify an imported variable ?

[yomgui]

I've tried this:

import MyPackage
if MyPackage.aVariable is None:
 MyPackage.aVariable = True

but when I tried to access MyPackage.aVariable from another file
(ie through an other import) the value is still None.


how can I do this

thanks

Re: how can I modify an imported variable ?

[yomgui]

hi,

your sample code works, but mine doesn't.
it must be a multi-thread issue.
I am certain that I am modifying MyPackage.aVariable
before using it.

Both threads are importing MyPackage,
but the modification of MyPackage.aVariable
is not seen by the other thread. is this possible ?

is there a turn around to allow it ?

thanks

Re: how can I modify an imported variable ?

[yomgui]

actually, it is not linked to threading but to the scope.
the second attempt to access MyPackage.aVariable
is inside the __init__ of a class
and this seems to be the problem.

I believe it is a genuine python bug.

opensg or openscenegraph

[yomgui]

Hi,

I need to use a scengraph for my python/opengl application
but I have trouble finding out which one I should use.

opensg or openscenegraph (OSG) ?

I suppose the quality of the python bindings will make the decision.

any advice ?

thanks

Hello,

I am attempting to use Popen() in a Windows service. I have a small
Win32 .exe that I normally run through the os.popen2() function. I've
written a class to work with the input and output parameters that are
passed and captured from this exe. When I use the class outside of a
service using either subprocess.Popen or os.popen2 work just fine.

When I use this class inside a Windows service it doesn't work. It
doesn't crash the service or anything but there are no values returned
from the Popen. Here's how I'm calling Popen:

p = subprocess.Popen( cmd, shell=True, bufsize=128,
stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE,
cwd="C:\\path_to_exe\\" )
p.wait()
(modbus_stdin, modbus_stdout)=(p.stdin,p.stdout)
lines = modbus_stdout.readlines()

While this doesn't fail there is nothing in the lines variable when it
finishes.

I am using Python 2.5 on a Windows XP Professional machine. Any help
would be greatly appreciated.

Best Regards,

Mark Shewfelt
