Simple example code.

Python recommends using super().

class B(A):
    def __init__(self):

obj = B()


Python call parent constructor

How to invoke the super constructor in Python?

Answer: Directly call the __init()__ method of a parent class to invoke its constructor

class Person:

    def __init__(self, name):
        print(name + " is a cricketer")

class Athlete(Person):

    def __init__(self, name):
        print(name + " is an athlete")

class FamousPerson(Person):

    def __init__(self, name):
        print(name + " is a famous person")

class Sachin(Athlete, FamousPerson):

    def __init__(self):
        Athlete.__init__(self, "Sachin")

        FamousPerson.__init__(self, "Sachin")

        Person.__init__(self, "Sachin")



Sachin is an athlete
Sachin is a famous person
Sachin is a cricketer

Note: super() is now equivalent to super(<containing classname>, self) as per the docs.
