I have two Python classes, say A and B, where B subclasses A. If I want to call a method in A from an overridden method in B I can either use:

B.inheritedAttribute('method_in_A')(self. *args) or: A.method_in_A (self, *args)

Can anybody explain me the differences between those two, because the second one seems (at least in the context of Zope Products) not always to work properly whereas the first one doesn't look very OO'ish and is (AFAIK) not a Python function but something coming from Zope. It is documented in the "ExtensionClass" documentation.

In my Zope installation (ZopeCVS), it is located in "lib/Components/ExtensionClass/doc/ExtensionClass.stx". Until recently, it has been elsewhere. Dieter
