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

🚀 Asian Markets Show Resilience Amid Geopolitical Tensions Asian stock markets continued their 'low open-recovery' trend on April 13, with Japan's Nikkei 225 and South Korea's KOSPI initially experiencing significant declines before quickly narrowing their losses. According to BlockBeats, this pattern reflects a decreasing sensitivity to geopolitical conflicts, such as the ongoing tensions involving Iran. Since the escalation of the Iran conflict, the market's Monday corrections have shown a consistent reduction in magnitude, moving from near double-digit losses to more moderate adjustments. This indicates a diminishing impact of geopolitical shocks on market sentiment. In trading dynamics, the 'Trump model' is being systematically priced in. This involves creating uncertainty through policy signals or strong statements during the week, followed by a softening stance or 'victory' outcomes over the weekend, which helps to restore expectations and drive a rebound in risk assets. As this framework is repeatedly validated, investors' willingness to trade on early-week volatility has decreased, leading to reduced selling pressure and a convergence in volatility patterns. #AsianMarkets#GeopoliticalTensions#Nikkei225#KOSPI#IranConflict#MarketResilience#TrumpModel#Volatility#RiskAssets#MarketSentiment#TradingDynamics#InvestorBehavior
