Hi,
I'm using python 2.4 and windows XP.
I have two packages in the windows version of python in site-packages.
They are PyVisa and ctypes, and both live in
c:\python24\lib\site-packages
I'd like to move these to the cygwin version of python on the same
system. I tried copying the PyVisa and ct

How about adding a step:
generate your class to a file
import the file as a module.
bind a name in "module" to the class in the imported module.

Thanks, Heiko, I'll give this a try. In the meantime, I'll try to explain what exactly I mean.Basically, I want the ability to reference a variable just as I am able to set a variable (or attribute) on the fly. For instance, say the user has the following list in a text file: [butter, cream, eggs

Try changing that to exec ~ in testModule.__dict__
