I discovered ruff earlier this year as the project was really taking off. It’s a python linter, and very recently now a formatter too. Its main selling points are that it is insanely fast and implements features previously provided by dozens of different tools. It was a pretty easy sell at work due to its speed, and the guy who initially wrote it now has a startup and they seem intent on expanding to cover more tool categories. It’s been a huge improvement for my work as a python dev.
