UV is fast, like FAST. Plus, it removes the need for pyenv (for managing different Python versions) and pip for me. Plus, no need to activate env or anything, `uv run ...` automatically runs your code through the env.

It's a nice software.

I don't see a way to change current and global versions of python/venvs to run scripts, so that when I type "python" it uses that, without making an alias.

If they're your scripts (i.e. your writing/editing them) then you can declare dependencies following the PEP723 format and uv will respect that.

I specifically want to run "python", rather subcommands for some other command, since I often I want to pass in arguments to the python interpreter itself, along with my script.

You can use "uv run python script.py" to the same effect.
