Python Coding challenge - Day 918| What is the output of the following Python Code?

 Code Explanation:

1. Defining the Class

class Money:

A class named Money is being created.

It will represent a value (like money amount) stored in x.

2. Constructor (__init__)

    def __init__(self, x):

        self.x = x

__init__ runs when an object is created.

It stores the passed number x into an instance variable self.x.

So each Money object holds a numeric value.

3. Defining __add__ (Operator Overloading)

    def __add__(self, other):

        return Money(self.x + other.x)

What this means:

Python calls __add__ when the + operator is used between two objects.

other refers to the second object on the right side of +.

Inside this method:

self.x + other.x adds the values from both objects.

A new Money object is returned containing the sum.

This is called operator overloading.

So instead of raising an error like normal objects,

using m1 + m2 creates a new Money object with combined value.

4. Creating Two Money Objects

m1 = Money(10)

m2 = Money(5)

m1.x = 10

m2.x = 5

5. Adding Two Money Objects

(m1 + m2)

Python translates this into:

m1.__add__(m2)

Inside __add__:

self.x = 10

other.x = 5

Computes 10 + 5 = 15

Returns a new Money object where x = 15

6. Printing the Value

print((m1 + m2).x)

(m1 + m2) returns a Money object with x = 15

Accessing .x prints the stored number

So the output is:

15

Final Result

Output:

15
