Python Coding challenge - Day 1107| 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.

2️⃣ Creating a Class Variable

x = 5

Explanation

x is a class variable.

It belongs to the class, not to individual objects.

All objects initially share this value.

3️⃣ Creating First Object

a = A()

Explanation

Creates an instance a of class A.

a can access class variable x.

4️⃣ Creating Second Object

b = A()

Explanation

Creates another instance b.

Both a and b currently share:

x = 5

5️⃣ Modifying Variable via Object

a.x = 10

Explanation ⚠️

This does NOT change the class variable.

Instead, it creates a new instance variable x inside object a.

👉 Now:

A.x = 5      # class variable

a.x = 10     # instance variable (new)

b.x = 5      # still uses class variable

6️⃣ Printing Values

print(A.x, a.x, b.x)

Explanation

A.x → class variable → 5

a.x → instance variable → 10

b.x → no instance variable → uses class variable → 5

📤 Final Output

5 10 5
