Python Coding challenge - Day 1128| What is the output of the following Python Code?

 

Code Explanation:

🔹 1. Class Definition

class Point:

✅ Explanation:

A class named Point is created.

It represents a point (or object) with a value x.

🔹 2. Constructor (__init__ method)

def __init__(self, x):

    self.x = x

✅ Explanation:

This method runs when an object is created.

self → current object.

self.x = x:

Creates an instance variable x.

Stores the value passed during object creation.

🔹 3. Operator Overloading Method (__add__)

def __add__(self, other):

    return Point(self.x + other.x)

✅ Explanation:

__add__ is a magic method used to overload the + operator.

It is called when you do:

obj1 + obj2

Parameters:

self → left object (p1)

other → right object (p2)

🔍 What it does:

Adds values:

self.x + other.x

Creates a new Point object with the result.

Returns that new object.

🔹 4. Creating First Object

p1 = Point(2)

✅ Explanation:

A Point object is created.

self.x = 2

🔹 5. Creating Second Object

p2 = Point(3)

✅ Explanation:

Another object is created.

self.x = 3

🔹 6. Adding Objects

p3 = p1 + p2

✅ What happens internally:

Python converts this into:

p1.__add__(p2)

Inside __add__:

self.x = 2

other.x = 3

Result:

2 + 3 = 5

New object created:

Point(5)

Stored in p3

🔹 7. Printing Result

print(p3.x)

✅ Explanation:

p3 is a Point object with:

x = 5

Output:

5

🎯 Final Output

5
