Re: what is the name of your super class?

2010-02-24 Thread Chris Hunter 
Using 2.6, what I saw was that I had to ask for __bases__ from the __class__
attribute of my object. So given your example, I'd check:

c.__class__.__bases__[0].__name__

And for the immediate superclass, this also seems to work:

c.__class__.__base__

This is strange. When I duplicate your code, thanos, I get an error that
says:
AttributeError: SubClass instance has no attribute '__bases__'

What's different about my setup?
I'm running Python 2.5.3

How about:

>>> class MySuperClass: pass
...
>>> class MySubClass(MySuperClass): pass
...
>>> c = MySubClass
>>>
>>> c.__bases__[0].__name__
'MySuperClass'

What I always ask develoeprs hwo join my team is "Please read the

This is an old document, but is useful for understanding class structure in
python:
http://www.python.org/download/releases/2.2/descrintro/

I think you might want the subclass.__class__ method.
