[Zope] exposing properties to python

[Joe Little]

Hello,

I am developing all my logic in python classes and using Zope for the 
presentation so that I can use CLI and other toolsets against the same 
objects.

In my particular case, I need to expose properties (either in property 
sheets or product-properties ($64K question is what is better to use!)) 
via python scripts either when I instantiate a ZClass based on the 
python base-class or in a post instantiation method in that base-class. 
I can't find any good python examples throughout the zope.org site. 
almost everything is either zclass-built and thus using property sheets 
via DTML

I'm not on the list, so any answers, please send to me directly if not 
to the list as well.

Also, if I shouldn't use product properties or product-instance property 
sheets, what should I use to communicate to python scripts from an 
add_form constructor or the like? I am used to python programming, but 
the Zope<->Python bridge hasn't made any sense to me thus far.
