Python Coding challenge - Day 899| What is the output of the following Python Code?

 Code Explanation:

1. Class Definition

class Test:

Explanation:

This line defines a class named Test.

A class is a blueprint used to create objects.

2. Constructor Method (__init__)

def __init__(self, x):

Explanation:

__init__ is a special constructor method.

It is called automatically when a new object is created.

self refers to the current object.

x is a parameter passed while creating the object.

self.x = x

Explanation:

This line stores the value of x inside the object.

It creates an instance variable named x.

3. Operator Overloading Method (__add__)

def __add__(self, other):

Explanation:

__add__ is a special method used for operator overloading.

It allows us to use the + operator with class objects.

self → first object

other → second object

return self.x + other.x

Explanation:

This adds:

self.x → value from first object

other.x → value from second object

It returns the sum of the two values.

4. Object Creation

obj1 = Test(5)

Explanation:

Creates an object obj1.

Calls the constructor: self.x = 5

So, obj1.x = 5

obj2 = Test(10)

Explanation:

Creates another object obj2.

Calls the constructor: self.x = 10

So, obj2.x = 10

5. Addition Operation

print(obj1 + obj2)

Explanation:

obj1 + obj2 automatically calls:

obj1.__add__(obj2)

Which returns:

5 + 10 = 15

Final Output

15
