How to get the parents of a Python class?

Question

How can I get the parent class(es) of a Python class?

Answer 1

Use bases if you just want to get the parents, use __mro__ (as pointed out by @naught101) for getting the method resolution order (so to know in which order the init's were executed).

Bases (and first getting the class for an existing object):

>>> some_object = "some_text"
>>> some_object.__class__.__bases__
(object,)

For mro in recent Python versions:

>>> some_object = "some_text"
>>> some_object.__class__.__mro__
(str, object)

Obviously, when you already have a class definition, you can just call __mro__ on that directly:

>>> class A(): pass
>>> A.__mro__
(__main__.A, object)
