Python Coding challenge - Day 972| What is the output of the following Python Code?

 

Code Explanation:

1. Defining Class A

class A:

This line defines a class named A.

The class will be used to create objects.

2. Defining the __new__ Method

    def __new__(cls):

__new__ is a special method responsible for creating a new object.

It is called before __init__.

cls represents the class A.

3. Creating the Object in __new__

        return object.__new__(cls)

object.__new__(cls):

Allocates memory for a new instance of A.

Returns that instance.

Because a valid object is returned, Python proceeds to call __init__.

4. Defining the __init__ Method

    def __init__(self):

__init__ initializes the already-created object.

self refers to the instance returned by __new__.

5. Printing Inside __init__

        print("init")

This line executes during object initialization.

It prints the string "init".

6. Creating and Printing an Object

print(A())

Execution Flow:

A() is called.

__new__ creates and returns an object.

__init__ runs and prints "init".

print() prints the object’s default representation.

7. Final Output

init
