Hi Ppl,
We created a DLL using cygwin and have written a class based python module
for the same. We have created a sample script for the class based python
module, that creates an object of the class and calls various methods in the
class. This Test script works fine while I run it from IDLE. Howe
class P():
pass
class C(P):
pass
Can I get P from C?
IOW, can I get a reference to the object P from the object C? This should be
obvious one way or the other, but I haven't been able to find the answer.
Regards,
John

This is not exactly fresh (it was written back in March), but it's the first
time I saw it and I thought I'd share. Barry Warsaw, one of the lead Python
developers, describes one of his most ... interesting ... debugging
experiences.

I'm writing a Scheme interpreter and I need to be able to create and return
a Python function from a string.
This is a port of another Scheme interpreter I wrote in Scheme. What I'm
trying to do looked like this:
