Update script for Python3

[captaintrav]

This script does the trick, but does not work on Ubuntu 22.04 since 'python' (python 2.7) is not installed.

If you install the python-is-python3 package it works, but maybe the script could be updated to call python3 instead of 'python' does not exist. Since it's just a one-liner it works fine with a python 3.x interpretter.

Works for Debian 12 Bookworm by installing python-is-python3, thanks for the trick.
