the thing you're looking for is "__bases__"

(it's called "base class" in python, and you can
have more than one)

>>> class A:
...     pass
...
>>> class B(A):
...     pass
...
>>> B.__bases__
(<class __main__.A at 795410>,)

to check if a class is a subclass to any other
class, use "issubclass":

>>> issubclass(B, A)
1
>>> issubclass(A, B)
0

hope this helps!
