class MyClass(object):
    def a(self):
        pass
    b = [a]

# Get the reference to a from the list
a = MyClass.b[0]

# How do I get the class a was defined on? Is it even possible?
# On Python 3, I can use __qualname__. This isn't around on Python 2.

@alexsv I've tried getting the code and the only thing you get is

    def a(self):
        pass
