Python Coding challenge - Day 1162| What is the output of the following Python Code?

 

Code Explanation:

🔹 1. Importing asyncio

import asyncio

✅ Explanation:

Imports Python's asyncio module.

Used for asynchronous programming.

In this code, asyncio is imported but not actually used.

🔹 2. Defining an Async Function

async def func():

✅ Explanation:

async def creates an asynchronous function.

Also called a coroutine function.

⚠️ Important:

This is NOT a normal function.

Example:

def normal():

    return 10

returns value immediately.

But:

async def func():

    return 10

returns a coroutine when called.

🔹 3. Return Statement

return 10

✅ Explanation:

If the coroutine is executed,

it will eventually return:

10

But execution hasn't happened yet.

🔹 4. Calling the Async Function

x = func()

🔍 What most beginners think:

x = 10

❌ Wrong

✅ What actually happens:

Calling:

func()

creates a coroutine object.

So:

x

stores:

<coroutine object func at ...>

🔹 5. Why Function Doesn't Execute?

Because async functions must be:

await func()

or

asyncio.run(func())

to actually run.

Without that:

func()

only creates a coroutine object.

🔹 6. Checking Type

print(type(x))

✅ Explanation:

Python checks type of:

x

which is a coroutine object.

🔹 7. Result

Output becomes:

<class 'coroutine'>

🎯 Final Output

<class 'coroutine'>
