Breaking Free from Virtual Environments Python's New Paradigm for 2026
summary
Claim: developers no longer need to manage venvs by hand because two practical approaches work today. One is temporary virtual environments via UV/UBX or pipx that create a throwaway venv to run tools (examples: ubx run format, pipex run build, GitHub Actions images ship pipex), the other is inline script metadata (PEP 723) where a script lists Python and deps and UV/UBx auto-creates envs (ubx add-script demo). Also: pip-tools/poetry/ry address dependency pinning and reproducible installs.
