Nathaniel J. Smith's PyCon 2018 talk introducing Trio, a Python concurrency library designed around usability and structured concurrency. He live-codes a problem and analyzes pitfalls in other async libraries.
Recommended as a clear introduction to structured concurrency and as an explanation of subtle asyncio bugs that Trio avoids.
“one of the best explanations I've seen about what subtle bugs are easy to make with asyncio”
3 Hacker News comments link this video. Each one links back to its thread.
The video (or blog post) below is one of the best explanations I've seen about what subtle bugs are easy to make with asyncio, why it's easy to make them, and how the trio library addresses them. But yes, consider alternatives before you pick asyncio as your approach! Talk: ▶ this video Blog post: [link]

Great list. That last suggestion (Multiple requests) can be tough to implement correctly, I think it's usually called Happy Eyeballs: ▶ this video
