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

when we first encounter an obstacle in our life, we struggled. & if we keep our head up & stay strong, we will eventually learn to overcome it. & that's how life goes, when we focus on the goal, no matter what happens, we'll learn to overcome each obstacle that comes upon us. & when the same obstacle keep on repeating, eventually it stops affecting us as much as the first time because we became used to it. but, at some points, there will be times when that same obstacle, same rock, managed to put us in despair - again. because we're tired. exhausted. sometimes not physically, but very emotionally and mentally. and we wonder, until when? what more should I do now? & why? rest, dear self. but don't you quit. & most important, don't let it turns you into a bitter person because you surely don't want that to happen. grow from this, please. #thoughts#notetoself @quietworld🍃

🍂 something you dislike happened? you couldn't get something you wish for? you have been disappointed and someone hurt you? you lost someone? you failed at something you hope you're good at? and you feel sad about it? then be so. feel sad. be sad. cry if you must. cry your heart out. let it out. it heals to cry. it heals to allow yourself to feel things; be human. because yes it is difficult to go through those things. & that doesn't mean that you are weak. to feel those feelings are not a sign of weakness at all ; just that we are human, we are born with the ability to feel those emotions. your strength is not determined by your ability to suppress emotions, but by your ability to overcome it; by not letting it controls yourself longer than it should be. there's light at the end of the tunnel if you keep going. #thoughts#notetoself#selfreminder#strength#positivity#sadness#motivation @quietworld🍃
