Code Explanation:
1. Defining Class A
class A:
Creates a class named A.
This class will contain methods that objects of class A can use.
2. Defining Method in Class A
def value(self):
Declares a method called value inside class A.
self refers to the instance of the class.
3. Returning Value from Class A
return 2
When value() is called on A, it will return the integer 2.
4. Defining Class B (Inheritance)
class B(A):
Defines a class B that inherits from class A.
This means B automatically gets all methods of A unless overridden.
5. Overriding Method in Class B
def value(self):
Class B creates its own version of the method value.
This overrides the version from class A.
6. Using super() Inside B’s Method
return super().value() + 3
super().value() calls the parent class (A) method value().
A.value() returns 2.
Then + 3 is added → result becomes 5.
7. Calling the Method
print(B().value())
B() creates an object of class B.
.value() calls the overridden method in class B.
It computes 2 + 3 → 5.
print() prints 5.
Final Output
5
