The __init__() method doesn't have to return a value. Of course it can if you like, but Python will just ignore the __init__ is a special Python method (also called dunder method) that is automatically called when memory is allocated for a new object. As it quickly became tiresome to say under-under-method-under-under Pythonistas adopted the term “dunder methods”, a short form of “double under.” Then, it calls class A's __init__ function with *args. Python sees the * in front of args and "unpacks" the list into arguments. In this example, when class B's __init__ function calls class A's __init__ function, it will be passed the arguments 2, 3 (i.e.

You can call the constructor method to create an object (=instance) from a class and initialize its attributes. __init__ is one of the reserved methods in Python. In object oriented programming, it is known as a constructor.
