Python Coding challenge - Day 454| What is the output of the following Python Code?

 

Code Explanation:

1. Class Definition

class MyCallable:

This line defines a class named MyCallable.

A class is a blueprint for creating objects.

2. Special Method __call__

def __call__(self, x):

Defines a special method inside the class.

__call__ allows an object to be called like a function.

It takes self (the object itself) and x (an input value) as parameters.

3. Return Statement

return x * 2

This line returns the result of x * 2.

It doubles the input value x.

4. Creating an Object

obj = MyCallable()

Creates an instance (object) obj of the MyCallable class.

5. Calling the Object like a Function

print(obj(3))

Calls the object obj with argument 3.

Internally, Python automatically runs obj.__call__(3).

3 * 2 is calculated, which equals 6.

The print function prints the output 6.

Final Output

6
