Chromebook - The Ultimate Mobile Development Device and Python

I'm a newbie when it comes to development and I need a starting point.  Recently, I inherited a Chromebook that I bought my nephew when his broke (sort of - it was resurrected by Best Buy).  After getting it to work again, I got it back.  As a Mac and Windows user, what would I have a Chromebook for?  Having no need for more than one machine, it sat there for a couple of weeks.  So I'm thinking while I have a need to improve my skills for the workplace of tomorrow, maybe I can use the Chromebook for building and improving on those skills.

So, I'm going to start as a newbie - I'll need a starting point, I'll need to make mistakes and learn from them, and I will gauge how the $300 Chromebook compares to my older an more expensive MacBook (from 2016) and a Windows tablet (I got it as a work laptop but it is too slow for massive Excel and database use) that I have turned it into a machine to learning cyber security.

The starting point for my will be Python.  More at Clouding Around.
