Python Coding challenge - Day 703| What is the output of the following Python Code?

 

Code Explanation:

1) import asyncio

Brings in Python’s asynchronous I/O library.

We’ll use it to run coroutines with an event loop.

2) async def f():

Defines coroutine function f.

Calling f() returns a coroutine object (doesn’t run yet).

Body

return 5

When awaited, f immediately finishes and yields 5.

3) async def g():

Defines another coroutine g.

Body

return await f() + 10

f() creates a coroutine; await f() runs it and gets its result.

Operator precedence makes this equivalent to:

return (await f()) + 10

So: await f() → 5, then add 10 → return 15.

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

asyncio.run(g()):

Creates an event loop,

Runs coroutine g() to completion,

Returns its result.

print(...) prints that result.

Output

15
