[Zope] get context in python product

[zope-mailinglist]

hello

does anybody now, how to get the context from which a specific method is
called in a python product
like in python scripts or dtml

i dont wanna use DTMLFile or HTMLFile Classes

i want to implement a function which recursively goes upwards in an object
tree if a property has a specific value till it gets another value, but i
cant get the context from where the method is called.

thx
