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

🌍 In Chile's Atacama Desert, rare fog called "camanchaca" drifts inland from the Pacific. Some plants here survive by absorbing water directly from this fog, not from rainfall. ✨ #desert⚡#arid⚡#adaptation⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels

🌍 Some arid desert landscapes feature ancient, dried-up riverbeds called wadis that can flood suddenly after rare rains, quickly turning from bare channels to rushing streams in a matter of hours. ✨ #desert⚡#arid⚡#landscapes⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels

🌍 Libya’s Libyan Desert holds sand seas with dunes reaching up to 180 meters tall. These giant dunes constantly shift with the wind, creating landscapes that can look completely different in just a few years. ✨ #desert⚡#dunes⚡#arid⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels

🌍 In the Taklamakan Desert of China, some sand dunes reach up to 300 meters tall. Shifting winds keep these giant dunes moving, constantly reshaping the landscape year after year. ✨ #deserts⚡#dunes⚡#arid⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography🌍

🌍 The Atacama Desert in Chile is so dry that some weather stations have never recorded rain. Its Mars-like soils are studied by scientists searching for signs of life in extreme environments. ✨ #desert⚡#extreme⚡#arid⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography🌍

🌍 The Namib Desert is thought to be the oldest desert on Earth, with arid conditions lasting for at least 55 million years—far longer than any other known desert. ✨ #desert⚡#Namib⚡#arid⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography🌍
