Here's a good function header given the following:
I wrote the below code

    class FakeHTTPConnection(object, ):
        def __init__(self, *args, **kwargs):
            pass
        def getresponse(self):
            if len(FAKE_RESPONSE_STACK):
                return FAKE_RESPONSE_STACK.pop()
            return utils.FakeHTTPResponse()
        def request(self, *_args, **_kwargs):
            pass
        def close(self):
            pass
    def fake_get_conn_class(self, *args, **kwargs):
        return FakeHTTPConnection
    stubs.Set(Store, '_get_conn_class', fake_get_conn_class)

What's a good function header?
