Python Coding challenge - Day 849| What is the output of the following Python Code?

 

Code Explanation:

1. Class Definition Begins

class A:

You define a class A.

This is a blueprint for creating objects.

2. Method Inside Class A

    def show(self):

        return "A"

A method named show() is created.

When this method is called, it returns the string "A".

3. Class B Inherits Class A

class B(A):

Class B is created.

It inherits from class A, meaning B gets all attributes/methods of A unless overridden.

4. Overriding the show() Method in Class B

    def show(self):

        return super().show() + "B"

Class B overrides the show() method of class A.

super().show() calls the show() method from the parent class A, which returns "A".

Then "B" is added.

So the full returned string becomes: "A" + "B" = "AB".

5. Creating an Object of Class B

obj = B()

An object named obj is created using class B.

This object can use all methods of B, and inherited methods from A.

6. Calling the show() Method

print(obj.show())

Calls B’s version of show().

That method calls super().show() → returns "A"

Adds "B" → becomes "AB"

Finally prints:

AB

Final Output: AB
