This is a script to install Python on a Chromebook.
It may work on other Debian Linux systems too.

This will:
1. Install prerequisites needed for Python on a typical Chromebook
2. Install Python 3 version that you choose

It will not install pip and virtualenv.  There is a separate script to do that.

Warning - Use this script at your own risk.  It may not work on all Chromebooks or setups.
This has been tested on a clean powerwashed Google Pixelbook.
If a step fails, the script will stop.
