Python Coding challenge - Day 583| What is the output of the following Python Code?

 

Code Explanation:

Line 1: Class Definition

class A:

This defines a new class A.

Line 2: Class Variable Declaration

x = 5

A class variable x is defined and initialized to 5.

This is shared across all instances unless overridden.

At this point:

A.x == 5

Line 3–4: Constructor (__init__) Method

def __init__(self):

    self.x = A.x + 1

When a new object of class A is created, the constructor runs.

self.x = A.x + 1 sets an instance variable x for that object.

A.x is 5, so:

self.x = 5 + 1 = 6

This does not modify the class variable A.x — it creates a new instance variable x.

Line 5: Object Creation

a = A()

An object a of class A is created.

During initialization, self.x is set to 6.

Line 6: Print a.x

print(a.x)

This prints the instance variable x of object a, which is 6.

Output:

6

Line 7: Print A.x

print(A.x)

This prints the class variable x, which is still 5.

Output:

5

Final Output:

6

5
