I have used Terry's code to write a script to find all of the the .pyc
files on my system that were compiled with the 2.3 version of the
compiler, and I have removed these files.
But my underlying problem still occurs: somewhere somebody is calling
for the 2.3 version of the Python vm .dll and not finding it. This is
happening under Pydev/Eclipse and my only recourse is to blow Eclipse
away using Task Manager.
So maybe I have a .pyd file somewhere that is a 2.3 extension.
Is there a way to examine .pyd files to see if they were built for
Python 2.3?
Finally, are there any other possible file extension types that I should
be looking at?
Thanks,
Don.

There's a "Magic Number" in the first 2 or 4 bytes, (depending on whether
you consider the \r\n part of the MN).
>>> f = open("pycfile.pyc", "rb")

>>> magic = f.read(4)

>>> print "Python release:", release
Python release: 2.4

[Tutor] Version of a .pyc file
I want like to write a script to scan all of the .pyc on my pythonpath to find out if they were built with Python 2.3 or 2.4. How can I tell if a .pyc file was built with 2.3 or 2.4? Thanks, Don. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
