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

🌎 Spectacular animal migrations include the annual journey of monarch butterflies, which travel up to 4,800 kilometers from Canada and the U.S. to central Mexico. These butterflies navigate using a combination of environmental cues and an internal sun compass in their antennae. ✨ #migration⚡#butterflies⚡#nature 👉subscribe Interesting Planet 👉more Channels ​

🌎 Monarch butterflies complete a multigenerational migration from Canada to central Mexico, traveling up to 4,500 kilometers. No single butterfly makes the entire round trip; several generations are born and die along the way. ✨ #butterflies⚡#migration⚡#insects 👉subscribe Interesting Planet 👉more Channels ​

🌎 Each year, monarch butterflies migrate up to 4,800 kilometers from Canada and the northern United States to overwinter in central Mexico. Clusters of millions gather on oyamel fir trees, using environmental cues like the angle of sunlight to navigate. ✨ #migration⚡#butterflies⚡#insects 👉subscribe Interesting Planet 👉more Channels ​

🌎 Monarch butterflies in North America complete one of the longest insect migrations, traveling up to 4,800 kilometers from Canada and the U.S. to central Mexico. Each fall, millions gather in mountain forests, forming dense colonies that help them survive winter’s cold. ✨ #butterflies⚡#migration⚡#insects 👉subscribe Interesting Planet ​

🌎 Some butterflies taste with their feet! Tiny sensors on their legs let them “sample” leaves, ensuring they lay eggs only on the best plants for their caterpillars. ✨ #butterflies⚡#senses⚡#nature 👉subscribe Interesting Planet
