Example implementations of how Python's super() function works

super_examples.py

class A:
    def foo(self):
        print('A foo method')

    def bar(self):
        print('A bar method')


class B(A):
    def foo(self):
        print('B foo method')

    def bar(self):
        print('B bar method')
        super().bar()


class C(B):
    def foo(self):
        print('C foo method')

    def bar(self):
        print('C bar method')
        super().bar()  # this is the same as calling `super(C, self).bar()`


def main():
    c = C()

    print('calling inherited methods outside of the class')
    # First argument is the class to elevate from to find implementation of foo method.
    # So by passing in C you are saying, look at the parent classes of C for an implementation of foo.
    # Second argument is an object the method will be called on.
    super(C, c).foo()
    super(B, c).foo()

    print('calling super without arguments outside of a class won\'t work')
    try:
        super().foo()
    except RuntimeError as err:
        print(f'`super().foo()` throws Runtime Error {err}')

    print('\n')

    print('calling inherited methods inside of the class')
    c.bar()


if __name__ == '__main__':
    main()

Should output

calling inherited methods outside of the class
B foo method
A foo method
calling super without arguments outside of a class won't work
`super().foo()` throws Runtime Error super(): no arguments


calling inherited methods inside of the class
C bar method
B bar method
A bar method
