Just use UV, it's the future of python dependency management.

Damn, this was dope, I didn't know uv could be that helpful.

I started using Python Poetry and the simplicity of managing virtual environments is amazing.

I remember some time I hated virtual environments because I found them complicated, I downloaded an app from github and it didn't work because of the version of python and libs, and installed all the versions and then got back and found out my recent projects didn't work

I started using pixi at the beginning of the year. It does all the things uv does, but also includes conda repositories, so that you can also pin the versions of compiled libraries and great utilities that are not on pypi such as ripgrep, fd, tokei, direnv etc.

4:03 "Most" of Python's libraries?? Either all libraries follow it or you CAN'T rely on it. In my experience, semantic versioning is a lie, stuff breaks just often enough in those "minor" updates that it's not worth bothering with it.
