You did:

>>> class BaseHandler:
...     def foo(self):
...             print "Hello"
...
>>> class HomerHandler(BaseHandler):
...     pass
...
>>> test = HomerHandler()
>>> test.foo()
Hello
>>> isinstance(test, BaseHandler)
True
>>> isinstance(test, HomerHandler)
True
>>>

You could say test is a "BaseHandler of type HomerHandler"
