Maximum recursion depth error in Python when calling super's init. [duplicate]

Answer 1

First thing to consider: C inherits constructor from B (because it's not defined in C).

Second thing to consider: self.__class__ in __init__ invocation in C class is C, not B.

Let's analyze:

• C().__init__ calls super(self.__class__, self).__init__(v, v2) which is resolved to super(C, self).__init__(v, v2) which means B.__init__(self, v, v2).
• First argument passed to B.__init__ has a type C. super(self.__class__, self).__init__(v, v2) is again resolved to B.__init__(self, v, v2).
• And again, and again, and again. And there is your infinite recursion.

Answer 2

Giving the first parameter of super as the class name solves this issue.

class B(A):
    def __init__(self, v, v2):
        # Do some processing
        super(B, self).__init__(v, v2)
