Python Coding challenge - Day 1037| What is the output of the following Python Code?

 

Code Explanation:

1. Class Definition

class A:

This line defines a class named A.

Classes are blueprints for creating objects.

2. __new__ Method (Object Creation)

def __new__(cls):

__new__ is a special method.

It is responsible for creating a new instance of the class.

cls refers to the class itself (not an object yet).

2.1 Calling Parent’s __new__

return super().__new__(cls)

super().__new__(cls) calls the __new__ method of the parent class (object).

This actually allocates memory for the new object.

The newly created instance is returned.

If __new__ does not return an instance of cls, __init__ will not run.

3. __init__ Method (Object Initialization)

def __init__(self):

__init__ is called after __new__.

self refers to the already created object.

This method is used to initialize the object.

3.1 Print Statement

print("Init")

Prints the string "Init" when an object of class A is created.

4. Object Creation

A()

This line creates an object of class A.

Execution flow:

__new__ is called → object is created

__init__ is called → object is initialized

"Init" is printed

5. Output

Init
