Python Coding challenge - Day 895| What is the output of the following Python Code?

 

Code Explanation:1. Class Definition

class Info:

This line defines a new class named Info.

A class is a blueprint for creating objects.

Objects created from this class will store a value and display it in a custom format.

2. Constructor Method

    def __init__(self, n):

        self.n = n

__init__ is the constructor method.

It runs automatically when a new object is created.

n is the value passed while creating the object.

self.n = n stores that value inside the object as an instance variable.

3. __repr__ Magic Method

    def __repr__(self):

        return f"Info[{self.n}]"

__repr__ is a special (magic) method used to define how the object looks when printed.

It returns a formatted string showing the value of n.

So if n = 11, it will return:

Info[11]

4. Object Creation

i = Info(11)

This creates an object i of the Info class.

The constructor assigns:

i.n = 11

5. Printing the Object

print(i)

print(i) automatically calls the __repr__ method.

It prints the formatted string returned by __repr__.

Final Output

Info[11]
