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 essence of peace and love is fundamentally opposed to the act of killing an innocent creature, such as a sheep. Regardless of who advocates for such actions, participating in violence against a defenseless being aligns one with darkness and cruelty, not light. Even if this act is presented as divinely sanctioned, the truth remains that taking the life of an innocent animal—who struggles for its existence—is an act of oppression and a crime against compassion. No justification, religious or traditional, can erase the truth: to take a life that wants to live is an act of brutality. The deception of evil can be subtle, leading individuals to believe they are on the right path while actually fulfilling the desires of darkness. This act contradicts the principles of peace, love, and justice. It is far better to turn away from beliefs rooted in darkness and embrace true peace and justice. Truth cannot be erased. You are not following truth but a darkness whose consequences are evident in your actions. Where there is action against peace, love, and justice, darkness prevails. Alignment with peace, love, and justice cannot result in the suffering of a being that cries out, that does not want to die. #vegan#vegans#vegetarian#vegetarians#greenpath#scientific#science @GreenPathForAll🍀
