The Python standard library provides the asyncio module to facilitate writing high-performance concurrent code. By leveraging async/await syntax, it provides a high level API for creating and managing event loops, coroutines, tasks, and performing asynchronous I/O operations. It is used as a foundation for Python asynchronous frameworks that provide high-performance network and web-servers, database connection libraries, distributed task queues, etc. Multiple libraries and frameworks, such as FastAPI and aiohttp, are built on top of asyncio.
Christopher covers a recent Real Python tutorial about developing mixin classes to reuse code across multiple Python classes. He describes how mixins rely on multiple inheritance to combine features from different classes, enhancing flexibility and code reuse.
