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

 

Code Explanation:

1. Class Definition

class A:

Defines a new class A.

2. Class Variable

    x = 5

x is a class variable, meaning it's shared across all instances.

So A.x = 5.

3. Constructor Method

    def __init__(self):

        self.x = A.x + 1

__init__ is automatically called when an instance of the class is created.

Inside it:

A.x refers to the class variable, which is 5.

self.x = A.x + 1 evaluates to 6.

So, a new instance variable self.x is created and set to 6.

4. Creating an Instance

a = A()

This creates an object a of class A.

The constructor runs, setting a.x = 6.

5. Printing the Instance Variable

print(a.x)

Outputs the instance variable x of a.

Output: 6

6. Printing the Class Variable

print(A.x)

Outputs the class variable x of class A.

Nothing has changed it, so it remains 5.

Output: 5

Final Output:

6

5
