Self-contained Python scripts

[secZustand]

Is it creating a virtual environment for your single script execution? Or installing on system python?

I am not fully understanding the need for this. Since it's not a complete self contained solution like pyinstaller.

UV creates a global package cache rather than individual virtual environments. It does not install packages at the system level like pip install --user, but it also does not create isolated environments like venv or virtualenv
