Python Coding challenge - Day 456| What is the output of the following Python Code?

 

Code Explanation:

1. Class Definition

class MyClass:

Defines a new class named MyClass.

Classes in Python are used to create user-defined data structures.

2. Constructor Method (__init__)

    def __init__(self, values):

        self.values = values

__init__ is the constructor method that gets called when a new object is created.

It takes values as a parameter and assigns it to the instance variable self.values.

3. Special Method __getitem__

    def __getitem__(self, index):

        return self.values[index]

This special method allows objects of MyClass to use bracket notation (e.g., obj[1]).

It accesses elements of the internal self.values list by index.

4. Object Instantiation

obj = MyClass([1, 2, 3])

Creates an instance of MyClass with a list [1, 2, 3].

The list is stored inside the object as self.values.

5. Element Access Using Indexing

print(obj[1])

Uses the __getitem__ method to access the second element (index 1) of self.values.

Outputs 2, since self.values = [1, 2, 3].

 
Final Output
