Python Coding challenge - Day 718| What is the output of the following Python Code?


 Code Explanation:

1) import asyncio

Imports Python’s asyncio library.

Provides an event loop and tools to run asynchronous coroutines.

2) async def f():

Defines a coroutine function f.

Inside f:

await asyncio.sleep(0.1)
return 7

await asyncio.sleep(0.1) suspends the coroutine for 0.1 seconds without blocking the whole program.

After the wait, it returns 7.

3) async def g():

Defines another coroutine function g.

Inside g:

return await f() + 3

Calls f() (returns a coroutine object).

await f() suspends until f completes and gives result 7.

Adds 3 to it → result = 10.

4) print(asyncio.run(g()))

asyncio.run(g()):

Creates a new event loop.

Runs coroutine g() until it finishes.

Returns the result (10).

print(...) prints the result.

Final Output
10
