Best of PyCoder's 2022

#557 – DECEMBER 27, 2022

It is that time of year again, everybody is making lists. Hopefully you weren’t on the “naughty” one. 2022 has seen a lot of change in tech, from the release of Python 3.11 to the sudden surge in Mastodon use, the world of Python has been busy.

This week’s newsletter is a collection of the most popular articles and projects linked in 2022. Maybe you missed one, maybe you’ve got more time to read something in depth.

Here’s to you, dear reader. Thanks for continuing to be with us at PyCoder’s Weekly. I’m sure 2023 will be just as wild. Speaking of 2023, if you come across something cool next year, an article or a project you think deserves some notice, send it to us and it might end up in a future issue.

Happy Pythoning!
