If you're among the Python developers put off by asyncio's complexity it's time to take
another look. Asyncio is complicated because it aims to solve problems in concurrent network
programming for both framework and end-user developers. The features you need to consider are a
small subset of the whole asyncio API but picking out the right features is the tricky part.
That's where this practical book comes in. Veteran Python developer Caleb Hattingh helps you
gain a basic understanding of asyncio's building blocks—enough to get started writing simple
event-based programs. You'll learn why asyncio offers a safer alternative to preemptive
multitasking (threading) and how this API provides a simpleway to support thousands of
simultaneous socket connections. Get a critical comparison of asyncio and threading for
concurrent network programming Take an asyncio walk-through including a quickstart guidefor
hitting the ground looping with event-based programming Learn the difference between asyncio
features for end-user developers and those for framework developers Understand asyncio's new
async await language syntax including coroutines and task and future APIs Get detailed case
studies (with code) of some popular asyncio-compatible third-party libraries
