Question

If I have Python code

class A():     pass class B():     pass class C(A, B):     pass 

and I have class C, is there a way to iterate through it’s super classed (A and B)? Something like pseudocode:

>>> magicGetSuperClasses(C) (<type 'A'>, <type 'B'>) 

One solution seems to be inspect module and getclasstree function.

def magicGetSuperClasses(cls):     return [o[0] for o in inspect.getclasstree([cls]) if type(o[0]) == type] 

but is this a ‘Pythonian’ way to achieve the goal?

Answer 1

C.__bases__ is an array of the super classes, so you could implement your hypothetical function like so:

def magicGetSuperClasses(cls):   return cls.__bases__ 

But I imagine it would be easier to just reference cls.__bases__ directly in most cases.
