I can always cheat myself by looking at a few examples of code, but never quite grasp the details of how a mechanism works. That is when my ignorance of other interactions within the environment go overlooked. Sometimes I’ll struggle to get something else to work without knowing of other methods that were available and were better suited to handle that use case. This book is good if you at least scan through all of it quickly. Go through it a 2nd and 3rd time a little slower. And finally pick the pieces of it that fit into your implementation. It is worth the time you’ll spend before you repeatedly run headlong into walls you didn’t know were there beforehand.

I greatly recomend. Concurrent programming is a cumbersome topic, and sooner or later becames important in the daily of almost every programmer.

And trying to grasp such a cumbersome topic, only with loose texts on the internet, may be not the best choice. This book is great. And it is a bargain. Thank you Jason!

De los mejores libros que he leído.

En menos de una semana aprendí TODOS los conceptos de asincronía y cómo aplicarlos en Python.

SI quieres aprender asincronía en Python, este es tu libro.

Está en inglés, pero se entiende MUY bien.

I wasted some months with other Asyncio books. This one really is the jump-start it claims to be.

It is methodical, concise, and covers all the important topics you will need. It is unexciting and a little repetetive but the better for it. That makes it easy to dip into—you don't need to read the whole thing from cover-to-cover to get full use of it.

Crucially it covers the synchronization primitives. You won't get far without them. (My only slight gripe is it doesn't make clear that you need to allocate them within the event loop. Once you know that, it is obvious, but when you need a jump-start you don't know that yet.)

Highly recommended.
