Python Coding challenge - Day 1110| What is the output of the following Python Code?

 

Code Explanation:

1️⃣ Defining the Class

class A:

Explanation

A class A is created.

It will store a value and support + operation.

2️⃣ Constructor Method

def __init__(self, x):

Explanation

Initializes the object.

Takes a value x.

3️⃣ Storing Value in Object

self.x = x

Explanation

Stores the value inside the object.

Each object has its own x.

4️⃣ Overloading + Operator

def __add__(self, other):

Explanation

Defines behavior of + operator.

When we write:

a + something

Python calls:

a.__add__(something)

5️⃣ Type Checking Using isinstance

if isinstance(other, A):

Explanation

Checks if other is an object of class A.

Helps handle different types safely.

6️⃣ Case 1: Adding Two Objects

return self.x + other.x

Explanation

If both are objects of class A:

A(5) + A(10)

👉 Becomes:

5 + 10 = 15

7️⃣ Case 2: Adding with Non-Object

return self.x + other

Explanation

If other is not object of class A:

A(5) + 3

👉 Becomes:

5 + 3 = 8

8️⃣ Creating Object

a = A(5)

Explanation

Creates object a with value:

a.x = 5

9️⃣ First Print Statement

print(a + A(10))

Explanation

Calls:

a.__add__(A(10))

Since other is object of class A:

5 + 10 = 15

🔟 Second Print Statement

print(a + 3)

Explanation

Calls:

a.__add__(3)

Since 3 is not object of class A:

5 + 3 = 8

📤 Final Output

15

8
