7 / 7

What happens when this code runs?


import asyncio


async def work(name):
    print(f"{name} start")
    await asyncio.sleep(1)
    print(f"{name} end")


async def main():
    await work("A")
    await work("B")


asyncio.run(main())

It runs both tasks concurrently; total runtime ≈ 1 second

It runs sequentially; total runtime ≈ 2 seconds

The output order is unpredictable

It raises a RuntimeError because asyncio.run() cannot be used with multiple awaits
