Using Asyncio in Python: Understanding Python’s Asynchronous Programming Features By: Caleb Hattingh

Author: Caleb Hattingh

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 developers and end-user developers like you. 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 end-user developers gain a basic understanding of Asyncio’s building blocks–enough to get you 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 simple way to support thousands of simultaneous socket connections.
