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

🚀 Ondo Explores Challenges in Stock Perpetuals Stock perpetuals have faced persistent challenges, according to PANews. Ondo, a financial services company, has identified a three-layered structural explanation for these difficulties. The first issue is the inherent complexity of stock perpetuals, which can deter potential investors. Unlike traditional stock investments, perpetuals require a deeper understanding of financial derivatives, making them less accessible to the average investor. Secondly, the market infrastructure for stock perpetuals is not as developed as that for other financial instruments. This lack of infrastructure can lead to inefficiencies and increased costs, further discouraging participation. Lastly, regulatory uncertainties surrounding stock perpetuals contribute to their underperformance. The evolving nature of financial regulations can create an unpredictable environment, making it challenging for investors to commit to these instruments. Ondo's analysis highlights the need for improved education, infrastructure, and regulatory clarity to enhance the performance and adoption of stock perpetuals. #Ondo#StockPerpetuals#FinancialChallenges#InvestmentComplexity#MarketInfrastructure#RegulatoryUncertainty#FinancialDerivatives#InvestorEducation#FinancialRegulations#StockMarket#ONDO
