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

🪐 The James Webb Space Telescope has observed the galaxy JADES-GS-z7-01-QU, one of the most distant “quiescent” galaxies ever found, meaning it has stopped making new stars even though its light began traveling to us over 13 billion years ago. Seeing JADES-GS-z7-01-QU lets scientists study how some galaxies aged and shut down astonishingly early, offering a rare glimpse into the universe’s remote past when cosmic structures were just beginning to take shape. ✨ #galaxies⚡#distance⚡#telescopes⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels

🪐 The James Webb Space Telescope discovered that the distant galaxy JWST-ER1 has an unexpected bar-shaped structure, even though it formed just 2 billion years after the Big Bang. Bars are elongated collections of stars that stretch across the centers of galaxies, and finding one so early suggests galaxies began organizing themselves much faster than scientists once thought. ✨ #galaxies⚡#telescopes⚡#discovery⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries

🪐 Scientists at the SETI Institute have used the Allen Telescope Array to listen for possible signs of alien technology from over 20,000 star systems, including those with known exoplanets like Gliese 581 and Kepler-452. Although no artificial signals have been confirmed, this real-world search for extraterrestrial intelligence uses radio telescopes to scan for narrowband signals—kinds of signals rarely produced by nature, but which could indicate advanced technology elsewhere in the galaxy. ✨ #aliens⚡#radio⚡#telescopes⚡#exoplanets⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels
