Python Coding challenge - Day 1098| What is the output of the following Python Code?

 

Code Explanation:

1️⃣ Defining the Class

class A:

Explanation

A class named A is created.

It will be used to create objects with a value.

2️⃣ Constructor Method

def __init__(self, x):

Explanation

__init__ is a constructor.

It runs automatically when an object is created.

It takes parameter x.

3️⃣ Assigning Value to Object

self.x = x

Explanation

Stores the value of x inside the object.

Each object will have its own x.

4️⃣ Defining Operator Overloading

def __add__(self, other):

Explanation

This method overloads the + operator.

When you write a1 + a2, Python internally calls:

a1.__add__(a2)

self → first object (a1)

other → second object (a2)

5️⃣ Returning the Sum

return self.x + other.x

Explanation

Adds values stored in both objects.

Returns:

5 + 10 = 15

6️⃣ Creating First Object

a1 = A(5)

Explanation

Creates object a1.

Calls constructor → self.x = 5

7️⃣ Creating Second Object

a2 = A(10)

Explanation

Creates object a2.

Calls constructor → self.x = 10

8️⃣ Using + Operator

print(a1 + a2)

Explanation

Python calls:

a1.__add__(a2)

Which becomes:

5 + 10

📤 Final Output

15
