Python Coding challenge - Day 1156| What is the output of the following Python Code?

 

Code Explanation:

🔹 1. Decorator Function Definition

def deco(func):

✅ Explanation:

A function deco is created.

It takes another function (func) as argument.

🔍 In this code:

func will become:

show()

🔹 2. Wrapper Function Definition

def wrapper():

✅ Explanation:

wrapper is an inner function.

This function will replace original show().

🔹 3. Modified Return Value

return "Hi " + func()

✅ Explanation:

Calls original function:

func()

🔍 Original function returns:

"Python"

Then:

"Hi " + "Python"

becomes:

"Hi Python"

🔹 4. Returning Wrapper

return wrapper

✅ Explanation:

Decorator returns wrapper function.

So original function gets replaced.

🔹 5. Applying Decorator

@deco

✅ Explanation:

This is shortcut for:

show = deco(show)

🔍 What happens:

Original show() passed into deco

wrapper returned

show now points to wrapper

🔹 6. Original Function

def show():

    return "Python"

✅ Explanation:

Original function returns:

"Python"

But now it is wrapped by decorator.

🔹 7. Calling Function

print(show())

🔍 What actually runs:

wrapper()

🔹 8. Execution Inside Wrapper

Step 1:

func()

calls original:

show()

returns:

"Python"

Step 2:

Wrapper adds:

"Hi " + "Python"

Result:

"Hi Python"

🎯 Final Output

Hi Python
