Subject: Get reference to parent class from subclass?

class P():
    pass

class C(P):
    pass

Can I get P from C? 

IOW, can I get a reference to the object P from the object C? This should be obvious one way or the other, but I haven't been able to find the answer.

Regards,

John

You should be able to access what you need via the super() built-in. I am not entirely sure what you are trying to do...but I think usage of super is probably better than trying to access the base classes manually.
