Стандартная библиотека asyncio это стандарт (начиная с Py3.4) для работы с асинхронным кодом. Но эта библиотека достаточно низкоуровневая, со своими проблемами, устаревшими подходами.
Чтобы исправить это, были созданы разные обертки и альтернативы с реализацией популярных инструментов и паттернов асинхронного программирования. Это такие библиотеки как:
- trio: улучшает корректность выполнения, не оставляя потерянных корутин при ошибках, то есть предлагает Structured Concurrency из коробки.
- curio: упрощение синтаксиса и читаемости кода, больше похоже на работу с потоками.
- anyio: универсальная обертка над asyncio или trio плюс множество вспомогательных инструментов.
anyio используется в FastAPI как основная библиотека для работы с асинхронным кодом и вызовом синхронного кода из асинхронного.
В общем, рекомендую почитать про возможности anyio, возможно вы более не будете использовать чистый asyncio в своих проектах)
Это совсем не значит что дефолтный asyncio плох, он тоже даёт достаточный для работы функционал и продолжает развиваться. Например, в версии 3.11 появились TaskGroup, с похожим на trio функционалом. Так что он тоже актуален, просто придется больше написать кода самостоятельно.

🔥Tangem presents integrated with
💳Visacrypto wallet
Tangem has developed a new wallet that supports direct payments through the Visa payment system. The new product for business (B2B) and consumers (B2C) will be released under the #Tangem brand and is expected to be launched by the end of the year, Tangem chief technical officer (CTO) Andrey Lazutkin told Cointelegraph.
Tangem Hardware Wallet Technology Certified by Visa✅️
The new Tangem crypto wallet will support Tangem Pay, a payment technology that allows users to spend cryptocurrency directly from a self-custody wallet through payment terminals or online payment tools. Tangem Pay is based on a smart contract and comes with one card without a seed phrase, Lazutkin said.
This is a significant step towards bringing the traditional banking sector and digital assets closer together, making it easier for everyday users to navigate and benefit from both worlds.
The team recently announced support for tokens created on the #TON network and another 1800+ other cryptocurrencies from different blockchains, allowing you to swap between them through the DEX built into the application.
