Python Coding challenge - Day 992| What is the output of the following Python Code?

 Code Explanation:

1. Defining the Class

class Action:

A class named Action is defined.

This class will later behave like a function.

2. Defining the __call__ Method

    def __call__(self, x):

        return x * 2

__call__ is a special method in Python.

When an object is called like a function (obj()), Python internally calls:

obj.__call__()

This method takes one argument x and returns x * 2.

3. Creating an Instance

a = Action()

An object a of class Action is created.

Since Action defines __call__, the object becomes callable.

4. Calling the Object Like a Function

print(a(5))

Step-by-step:

Python sees a(5).

It translates this into:

a.__call__(5)

Inside __call__:

x = 5

5 * 2 = 10

The value 10 is returned.

5. Final Output

10

Final Answer

✔ Output:

10
