Python 3.14 was the star of the show in 2025, bringing official support for free-threaded builds, a new all-in-one installation manager for Windows, and subtler perks like the new template strings feature. Other great updates this year included a growing toolkit of Rust-backed Python tools, several new options for packaging and distributing Python applications, and a sweet little trove of third-party libraries for parallel processing in Python. Here’s our list of the 10 best and most-read stories for Python developers in 2025. Enjoy!
