What Does the Python Version Number x.y Actually Mean?

At work, we use uv to manage Python projects, which allows us to quickly install dependencies and lock sub-dependency versions. After returning from a period of leave, I routinely updated the packages on my computer and noticed that uv had a new version, so I updated it. However, after updating the uv.lock file in a project, I found that many wheels for dependencies had disappeared from the lock file. For example, here’s the configuration of the pyproject.toml file: ...

Python you let me down

Personally, I’m very disappointed about the some Python community people/projects. It’s been years that PEP 3000(the year was 2006) came up, but we need to wait years until Python 3.11(the year was 2022) to get real performance improvements? Why people keep using Python and spending lots of time to add typing which doesn’t have run time check instead of rewriting codes in Go to get huge speed up while enjoying static language’s safe static type? ...
