How to get the types of the parents of an object ?

[Mike C. Fletcher]

Finding object/class inheritence is common enough to have two builtin 
functions assigned to the task:

    isinstance( my_object, my_super_class )

    issubclass( my_class, my_super_class )

and, under Python 2.2, you can do silly things like:

    my_super_class in my_class.__mro__

Though that last one is almost certainly _not_ a good idea :) .  I'm 
just providing it to give you pointers as to things to search for in the 
docs if you really do want to get all super-classes (parents) of a 
class.  You could also search for __bases__ for the older Python 
versions (still available in 2.2, just not as convenient as __mro__).

Enjoy,
Mike
