astral silently dropped a clever uvx.sh to help builders reach a wider audience, no longer does a user need to have python installed prior to installing a python cli. It does have a hard requirement on having curl or wget available.

Such a fantastic use of uv, its so fast and flexible and does everything I need that next time I go to set up some more complex testing like this I’m going to lean towards it more than i would something like tox. In the post Daniel sets up matrix testing for testing out different versions of python with the same pytest test suite.

Good point to check on your uv cache if you are running low on disk space. I checked mine today, and it wasn’t too bad so I left it alone.

This is really interesting, the lazy uv scripts are really becoming quite appealing, especially for something like this to just pop out of an llm ready to run. The article features several examples of these one-shot prompt ideas that I suggest you give a try, and a prompt for creating them.

I’ve kinda fallen out of using direnv now that a lot of my projects use hatch, I generally just hatch shell into them. I just need to make sure I go through all of them and make my installer uv. Now I’ve been thinking about making uv my only needed dependency to run a python project and leaning more to something like uv run --with . uvicorn myapp --reload

I really like Trey’s steps to making an executable python script with uv

his old process seems to be the same with a new shebang

And here is the new format the the shebang followed by the metadata comment block defined in PEP 723.

uv now can install python for you. uv is inspired by rust’s cargo, an all in one fast package and installation manager. uv is so fast and becoming feature complete, it’s really changing the python packaging ecosystem.
