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

#grammar #soon #early #quickly @fluencyinenglish ❇️Soon, Early and Quickly Soon means ‘a short time after now’. Get well soon. (NOT Get well early.) We will launch a new edition of this book sometime soon. Soon can also mean ‘a short time after then’. It was difficult in the beginning, but I soon got used to it. (NOT It was difficult in the beginning, but I early got used to it.) @fluencyinenglish Early Early means ‘near the beginning of a period of time we are talking about’. Early does not mean soon. Compare: Early this week, I had a strange experience. (NOT Soon this week, I had a strange experience.) He had an accident early this month. He will soon have an accident if he continues to drive like this. (NOT He will early have an accident…) I get up early in the morning. (NOT I get up soon in the morning.) Early can mean ‘before the expected time’. I arrived early. Early can be used as an adjective. We will be grateful for an early reply. @fluencyinenglish Quickly There is a difference between soonand quickly. We use quickly to refer to the speed with which something is done. Soon means ‘before long’. I got dressed quickly. (= I didn’t take a lot of time to get dressed.) @fluencyinenglish
