taskgroup

a backport of asyncio.TaskGroup, asyncio.Runner and asyncio.timeout

background

This is a backport of the TaskGroup, Runner and timeout code from Python 3.12.8 to Python 3.9, Python 3.10 and Python 3.11.

operation

This project works by temporarily swapping the current task of a coroutine to a subclass of asyncio.Task with uncancel and context setting support. The advantage of this approach means that most of the operation of asyncio.Task will continue to be c-accelerated.

example

if sys.python_version >= (3, 11):
    from asyncio import run, TaskGroup, timeout
else:
    from taskgroup import run, TaskGroup, timeout

async def main():
    async with TaskGroup() as group:
        group.create_task(task1())
        group.create_task(task2())

run(main())
