Python doesn&#39;t wait for checkbox

The async context manager doesn't know anything about the asynchronous generator. Nothing in main knows about the asynchronous generator after you break, in fact. You've given yourself no way to wait for the generator's finalization.

If you want to wait for the generator to close, you need to handle closure explicitly:

async def main():
    async with async_context():
        gen = async_gen()
        try:
            async for _ in gen:
                break
        finally:
            await gen.aclose()

In Python 3.10, you'll be able to use contextlib.aclosing instead of the try/finally:

async def main():
    async with async_context():
        gen = async_gen()
        async with contextlib.aclosing(gen):
            async for _ in gen:
                break
