If you8217re among the Python developers put off by asyncio8217s complexity, it8217s 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. That8217s where this practical book comes in.  Veteran Python developer Caleb Hattingh helps you gain a basic understanding of asyncio8217s building blocks8213enough to get started writing simple event-based programs. You8217ll 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.
