Fun with uv and PEP 723

If PEP 723 is only an enhancement proposal does it work only because `uv` happens to support it?

Can you not use `uvx` with your script because it only works on packages that are installed already or on PyPi?

PEP 723 was incorporated (with modifications) into the official Python packaging specifications: https://packaging.python.org/en/latest/specifications/inline...

I don't think running with uv vs uvx imposes any extra limitations on how you specify dependencies. You should either way be able to reference dependencies not just from PyPi but also by git repo or local file path in a [tool.uv.sources] table, the same as you would in a pyproject.toml file.

uvx is useful to run scripts inside PyPi packages. It does not support running Python scripts directly

You can use uvx run scripts with a combination of the --with flag to specify the dependencies and invoking python directly. For e.g

uvx --with youtube-transcript-api python transcript.py

But you wont get the benefit of PEP 723 metadata.

PEP 723 is final and most relevant tools will support it:
