Python Coding challenge - Day 452| What is the output of the following Python Code?

 

Code Explanation:

Function Decorator Definition

def multiply(func):

    return lambda x: func(x) * 3

This is a decorator named multiply.

It takes a function func as input.

It returns a new lambda function:

lambda x: func(x) * 3

→ This means it calls the original function func(x) and multiplies the result by 3.

Decorating the add Function

@multiply

def add(x):

    return x + 2

The @multiply decorator wraps the add function.

So add(x) becomes:

lambda x: (x + 2) * 3

 Calling the Function

print(add(5))

When add(5) is called:

First: 5 + 2 = 7

Then: 7 * 3 = 21

So the result is 21.

Final Output

21
