For scripting... HIGHLY recommend putting your dependencies inline.

E.g.:

  #!/usr/bin/env python3
  # /// script
  # requires-python = ">=3.11"
  # dependencies = [
  #     "psycopg2-binary",
  #     "pyyaml",
  # ]
  # ///

Then -

  uv run -s file.py

How does this interact with your code editor or IDE? When you edit the file, where does the editor look for information about the imported third-party libraries?

Usually the VENV and import lines are enough

How do you determine where the venv is? AFAIK, uv run in script mode creates the venv in some random temporary directory.

I don’t know of a convenient way of doing it, but a clumsy way of doing it is to run this in your script:

  import os
  
  print(os.environ['VIRTUAL_ENV'] + '/bin/python')

Then, e.g. in VS Code, you bring up the command palette, run Python: Select Interpreter, and enter the result.

uv v0.6.10 has just been released with a more convenient way of doing this:

    uv python find --script foo.py

— https://docs.astral.sh/uv/reference/cli/#uv-python-find--scr...

Do you need a wrapper script for scripts in the PATH or execve? I would usualy chmod+x the script but I am not sure here.

If you want to make it work regardless of where uv is installed, you can use the following shebang line:

  #!/usr/bin/env uv run --script

Discussed here:

> Using uv as your shebang line

Since `env` doesn’t pass multiple arguments by default, the suggested line uses `-S`:

   #!/usr/bin/env -S uv run --script

Not at a laptop to try this right now, but shouldn't this be possible with the shebang? Something along the lines of:

    #!/home/tetha/Tools/uv run

Yes it is, I just converted my work scripts over this afternoon.

    #!/usr/bin/env uv run
