[mod_python] Module importing and classes

When you mentioned the circular import I did some research learned that indeed doesn't work. So yes, the solution I'm going for is to make individual modules (files) for all my 'index(req)' functions (which implement a state-machine with some sub-state-machines) and put the class definitions in extra module files which then can be imported by the the state-machine (index()) files...

I haven't tried it yet fully but in theory it should work... If not I'll post a simple example again =)

There should have been a section after that in the page returned in the browser.

Anyway, the problem is that you have a circular import, you shouldn't do it as not only will you get this problem, but mod_python will reimport both modules on every request even if you haven't changed them because of how dependency management between modules works. What you need to do is create a third file which contains the:

class WebGUI:
 def __init__(self):
   attribute = 0

definition and have webEdit.py import that so as to avoid the cycle.
