   Bringing multithreading to Python's async event loop▲82

   This project explores the integration of multithreading into the asyncio event loop in Python. While this was initially built with enhancing CPU utilization for FastAPI servers in mind, the approach can be used with more general async programs too. If you’re interested in diving deeper into the details, I’ve written a blog post about it here: https://www.neilbotelho.com/blog/multithreaded-async.html

    Practical Python Projects book release▲88

    Hi everyone! I just released the Practical Python Projects book! (https://practicalpython.yasoob.me) I am happy to announce the first version as a release candidate. I have poured a lot of love into writing this book and would love to hear what you guys think. (A limited 100% off and discount coupons at the end) This is not a pure beginner book. The book does assume some background Python knowledge. You need to know the basics like methods, functions, classes, and such. If I use something that is not typically covered in beginner Python books, I will explain it before I use it.…

    I wrote a book about Python▲181

    Hey HN! I wrote a book on programming called The Elements of Code. I put the entire book online here: https://elementsofcode.io/ When mentoring (usually new) programmers, I noticed there were a few common mistakes that seemed to account for about 80% of the complexity in their code. I couldn’t find a concise guide to fixing those mistakes, so I decided to write one. The title is an homage to The Elements of Style by Strunk and White, which is the classic guide for communicating well using prose. That guide is quite tactical in nature, and I wanted to parallel its focus in The…
