AnyIO and Structured Concurrency:

In Simple Words: AnyIO is an asynchronous compatibility library that works across both AsyncIO and Trio, enforcing structured concurrency where background tasks cannot outlive their enclosing scope.

python
import anyio

async def run_anyio_tasks():
    async with anyio.create_task_group() as tg:
        tg.start_soon(anyio.sleep, 1)
        tg.start_soon(anyio.sleep, 2)
