This talk is aimed at those that have at least intermediate experience in Python and have played around with asynchronous Python using asyncio or other libraries. I want the audience to learn from my mistakes! For instance, how easy it is to get into “callback hell” (and how to avoid/get out of it), how to screw up thread safety and deadlock yourself, and making code async but not actually concurrent.
I’ll talk through some anti-patterns and best practices that I learned the hard way. This includes proper concurrency, calling coroutines from synchronous code, working with threads and threadsafety, properly shutting down an async programs, and hidden “gotchas”.
