Is Python's tooling incredibly difficult, or am I just stupid? (sh.itjust.works)

So I'm no expert, but I have been a hobbyist C and Rust dev for a while now, and I've installed tons of programs from GitHub and whatnot that required manual compilation or other hoops to jump through, but I am constantly befuddled installing python apps. They seem to always need a very specific (often outdated) version of python, require a bunch of venv nonsense, googling gives tons of outdated info that no longer works, and generally seem incredibly not portable. As someone who doesn't work in python, it seems more obtuse than any other language's ecosystem. Why is it like this?

pip3 freeze > requirements.txt

I hate this. Because now I have a list of your dependencies, but also the dependencies of the dependencies, and I now have regular dependencies and dev-dependencies mixed up. If I'm new to Python I would have NO idea which libraries would be the important ones because it's a jumbled mess.

I've come to love uv (coming from poetry, coming from pip with a requirements/base.txt and requirements/dev.txt - gotta keep regular dependencies and dev-dependencies separate).

uv sync

uv run <application>

That's it. I don't even need to install a compatible Python version, as uv takes care of that for me. It'll automatically create a local .venv/, and it's blazingly fast.

I've never really spent much time with uv, I'll give it a try. It seems like it takes a few steps out of the process and some guesswork too.
