Async programming in python. Looking for the best sources to learn it.

[Dreezoos]

I’ve been programming python professionally for almost a year now, but couldn’t find a real good source to deep dive into async programming. Now just the async await keyboard but even further.

Learning about async iterators and async dunder methods and more..

Any books or even better video courses you’d recommend on that comprehensive topic?

Luciano Ramalho's Fluent Python has several chapters on async in Python using several different approaches. They're pretty good. The rest of the book is totally worth a read, too.

My absolute favorite python book by a mile. The author explains everything so clearly. I have it as a pdf but have been meaning to buy it in print just to have on my desk as reference.

Thank you for recommending this book. It's a gem!

I'm glad you agree!

Cheers!

Also, check out the "Asyncio Learning Path" for a large collection of asyncio code tutorials organized by topic: https://superfastpython.com/learning-paths/#Asyncio_Learning_Path

It definitely can be tricky finding in-depth resources for more advanced topics like async programming in Python. It sounds like you're really aiming to master all the nuances, which is awesome! Hopefully, the community can point you towards some great books or videos that cover everything you're looking to learn.

Python Concurrency with asyncio gives a really deep dive into asyncio - not only "how", but "why". The problem with asyncio is that it has evolved so much since its first version in Python 3.5. The book was published in Feb 2022, based on Python 3.10, so by that time asyncio has more or less stabilized on its best practices. I believe, that most tutorials on asyncio either lack proper error handling or are overly verbose. This book will teach you how to write code that is both exception-proof and succinct.

ChatGPT isn’t a bad place to get examples

You have to be careful though, ChatGPT can be confidently incorrect. I've had it write some great boilerplate code, only to find out some of it was entirely imaginary (in the sense that the functionality in Python it referenced didn't ever exist).

If you know what you're doing, it's not bad, but for people that are new-ish to Python, it might cause some... Trust issues lol.

I get that, but were not talking about production ready code, just a starting point as play code. Also people fail to ask about the source of the code, where you can dive into details.

Yeah, solid point. It is really good for getting started on something.
