What is super methon in python How to Call Method of a Particular Super Class...

super() Method:

super() is a built-in method that is useful to call the superclass constructors, variables, and methods from the child class.

Demo Program-1 for super():

class Person:

    def __init__(self,name,age):

        self.name=name

        self.age=age 

    def display(self):

       print('Name:',self.name)

       print('Age:',self.age) 

class Student(Person):

    def __init__(self,name,age,rollno,marks):

        super().__init__(name,age)

        self.rollno=rollno

        self.marks=marks

    def display(self):

        super().display()

        print('Roll No:',self.rollno)

        print('Marks:',self.marks) 

s1=Student('Durga',22,101,90) 

s1.display() 

Output:

Name: Durga

Age: 22

Roll No: 101

Marks: 90

In the above program, we are using the super() method to call the parent class constructor and 

display() method

#Demo Program-2 for super():

class P:

    a=10

    def __init__(self):

        self.b=10

    def m1(self):

        print('Parent instance method')

    @classmethod

    def m2(cls):

        print('Parent class method')

    @staticmethod

    def m3():

        print('Parent static method') 

class C(P):

    a=888

    def __init__(self):

        self.b=999

        super().__init__()

        print(super().a)

        super().m1()

        super().m2()

        super().m3()

c=C()

Output:

10

Parent instance method

Parent class method

Parent static method

In the above example, we are using super() to call various members of the Parent class.
