How can I check if a type is a subtype of a type in Python?

Question

How can I check if a type is a subtype of a type in Python? I am not referring to instances of a type, but comparing type instances themselves. For example:

Answer 1

Maybe issubclass?

>>> class A(object): pass
>>> class B(A): pass
>>> class C(object): pass
>>> issubclass(A, A)
True
>>> issubclass(B, A)
True
>>> issubclass(C, A)
False
