Python multiple inheritance constructor not called when using super()

Question

Consider the following code:

class A(object):
    def __init__(self):
        pass
class B(object):
    def __init__(self):
        self.something = \'blue\'         


        

Answer 1

Superclasses should use super if their subclasses do. If you add the super().__init__() line into A and B your example should work again.

Check the method resolution order of C:

>>> C.mro()
[__main__.C, __main__.A, __main__.B, builtins.object]

This article should clear things up.
