Hi
I have to check wheter a .py script is run within the debug or the
release version of an embedded python interpreter (in short, wheter
python24_d.dll or python24.dll is in use).
long version: I'm using ctypes to load my own dll. There exists 2
version of this dll - a debug and a release version (where one is linked
against debug C runtime dll and the other to release C runtime dll). Now
I have to change the name of the dll I want to be loaded by ctypes...
But how can I find out which of the dll I have to load?!
Thanks in advance!

calling GetModuleFileNa me (in kernel32.dll) on sys.dllhandle should give
you the name of the current Python DLL. something like this should work:
from ctypes import *
MAX_PATH = 500
filename = c_buffer(MAX_PA TH)
windll.kernel32 .GetModuleFileN ameA(sys.dllhan dle, filename, MAX_PATH)
filename = filename.value
</F>

You could use imp.get_suffixe s(). In a release build the returned list
will contain these entries
('.pyd', 'rb', 3), ('.dll', 'rb', 3)
in a debug build that will be
('_d.pyd', 'rb', 3), ('_d.dll', 'rb', 3)
Another way would be to look at the filename of any binary extension
module. _ctypes.__file_ _, for example: '.....\\_ctypes .pyd' vs.
'....\\_ctypes_ d.pyd'.

Thanks for your answers!
I prefer the proposal of Thomas Heller by using a small helper function
like this:
def IsDebugVersionR unning():
import imp
for suffix in imp.get_suffixe s():
if suffix[0] == '_d.pyd':
return True
return False
This works well for me. The
_ctypes.__file_ _
trick didn't work for me - I guess I've done something wrong...
One more question: Under linux this doesn't seam to work - as there is
always returned '.so' (not '_d.so') at least in my tests. Are there no
debug/release version issues like on windows? doesn't import the
python2.4-dbg (debian) binary different modules than python2.4?

Hi Folks,
We've been using Python embedded in an application for a while now,
where the Python dll is PythonNN.dll, NN being the version number, such
as Python24.dll.
Recently it was pointed out to me that Python can run in a debug or
release configuration and that you can specify this on the command line
using -O and -OO.

I use Visual C 2005 to develop my programs. One in particular is
crashing in very specific and hard to replicate situations, made worse
by the fact it only crashes when run -outside- the dev - as an exe,
not from the Debug option. If I try to launch the debug on the
crashing program, it'll close before the debugger opens. Any
suggestions as to how I should proceed? Thanks in advance.

How can i find out if a selected python interpreter (i only know the
