Отдельно разберём TaskGroup, который пришел на замену gather в Python 3.11. Ключевые отличия ▫️create_task() возвращает объект asyncio.Task, у которого есть соответствюущие методы управления. То есть у нас больше контроля ▫️это контекстный менеджер, который гарантирует что все таски будут остановлены по выходу из контекста ▫️ошибка автоматически отменяет незавершенные задачи, ▫️except* передает нам ExceptionGroup, в котором каждую ошибку можно обработать отдельно import asyncio import random async def do_it() -> str: if random.random() < 0.1: raise ValueError('Oops') delay = random.uniform(0.5, 1.5) await asyncio.sleep(delay) return delay async def main(): try: async with asyncio.TaskGroup() as tg: for _ in range(10): tasks.append(tg.create_task(do_it())) for t in tasks: print(t.result()) except *ValueError as e: for err in e.exceptions: print(err) asyncio.run(main()) Рекомендую изучить страницу Coroutines and Tasks из документации, где представлено больше интересных примеров и механизмов - таймауты - отмена задач - создание задач из другого потока #async
