asyncio is used as a foundation for multiple Python asynchronous frameworks that provide high-performance network and web-servers, database connection libraries, distributed task queues, etc.
asyncio is often a perfect fit for IO-bound and high-level structured network code.
asyncio provides a set of high-level APIs to:
Additionally, there are low-level APIs for library and framework developers to:
networking
, running subprocesses
