Python super arguments | Example code

The super() doesn’t know what class it’s being called in. we have to tell it which class’s parent’s function want to get. It is called a super argument in Python.

Python super arguments example

Simple example code in Python 3 works:- create a Vehicle class and want also to have a Car a class derived from it that calls the parent constructor.

class Vehicle:
    def __init__(self):
        print('Vehicle __init__() called')


class Car(Vehicle):
    def __init__(self):
        super().__init__()


car = Car()

Python multiple inheritance passing arguments to constructors using super

When dealing with multiple inheritances in general, your base classes should be designed for multiple inheritances.

class A(object):
    def __init__(self,a):
        self.a=a

class B(A):
    def __init__(self,b,**kw):
        self.b=b
        super(B,self).__init__(**kw)

 class C(A):
    def __init__(self,c,**kw):
        self.c=c
        super(C,self).__init__(**kw)

class D(B,C):
    def __init__(self,a,b,c,d):
        super(D,self).__init__(a=a,b=b,c=c)
        self.d=d
