Description

Installed distributions via importlib.metadata

#!/usr/bin/env python3
# Python installed package inventory
# Read-only: importlib.metadata lists local distributions and a count. Does not download.
# Exit 0 if packages can be listed, 1 if the environment is empty, 2 on metadata errors.
# Hosted on Runny.sh. Review the script page before you run it.
