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

Napoleon wasn’t short — about 1.69 m (5′5″). The “short” myth comes from unit differences and wartime caricature. 🇫🇷📏🗡️ [Source] @googlefactss #History#Napoleon#MythBusting#FrenchRevolution

The hymen is a small, flexible tissue at the entrance of the vagina. It doesn’t serve a specific purpose and can vary in size and shape. The hymen can stretch or tear naturally from activities like sports, tampon use, or sexual activity. Hymen myths are harmful and misleading: 1. The hymen isn’t a sign of virginity. 2. It doesn’t always "break" during intercourse; it’s flexible and can stretch. 3. No bleeding or pain is required for sexual activity—every experience is different. 4. The hymen should not define someone's worth or sexuality. 5. "Virginity restoration" surgeries are unnecessary and risky. The answer with the number 12 from [the poll a few days ago] was the only correct one. 🌸🩸🚫 [Read more] @googlefactss #HymenFacts#MythBusting#SexEd#Health#DidYouKnow

Many people believe rocks and minerals like rose quartz, amethyst, and moonstone have healing powers. These beliefs come from culture, symbolism, and psychology, not science. Ancient cultures gave stones meanings. Jade meant longevity. Turquoise meant protection. Quartz meant clarity. Modern crystal healing claims crystals carry energy that affects health. There is no scientific evidence for this. A study by Christopher French tested this with real and fake crystals. People did not know which they had. They reported similar feelings in both groups. This showed the effects came from expectation, not the crystals. They are still pretty though. 💎🔬🧠 [Read more 1] [Read more 2] [Read more 3] (Related poll) @googlefactss #crystals#science#facts#mythbusting#psychology#placebo
