Doug Hellmann: asyncio — Asynchronous I/O, event loop, and concurrency tools — PyMOTW 3

The asyncio module provides tools for building concurrent applications using coroutines. While the threading module implements concurrency through application threads and multiprocessing implements concurrency using system processes, asyncio uses a single-threaded, single-process approach in which parts of an application cooperate to switch tasks explicitly at optimal times. Most often this context switching occurs when the … Continue reading asyncio — Asynchronous I/O, event loop, and concurrency tools — PyMOTW 3
