Python Coding challenge - Day 863| What is the output of the following Python Code?

 

Code Explanation:

1. Class Definition

class Num:

A class named Num is created.

Objects of this class will store a number and support custom operations (like %).

2. Constructor Method

    def __init__(self, x):

        self.x = x

__init__ runs when a new Num object is created.

It assigns the input value x to the instance variable self.x.

Example: Num(20) → self.x = 20.

3. Operator Overloading: __mod__

    def __mod__(self, other):

        return Num(self.x // other.x)

This method is called when you use the % operator on Num objects.

Instead of normal modulo, this custom method performs floor division (//).

It returns a new Num object holding the result.

Example: 20 // 3 = 6.

4. Creating the First Object

n1 = Num(20)

Creates an object n1 where n1.x = 20.

5. Creating the Second Object

n2 = Num(3)

Creates an object n2 where n2.x = 3.

6. Using the % Operator

print((n1 % n2).x)

Calls n1.__mod__(n2) internally.

Computes 20 // 3 = 6.

Returns a new Num object with x = 6.

.x extracts the stored value.

Final Output

6
