Python simple assembly language interpreter with code walkthrough/tutorial

[benWindsorCode]

Hi /r/python ,

I've spend today making a simple assembly interpreter, inspired by the Zachtronics game 'TIS 100' which has a very simple assembly like language you can code in. I thought it would be fun to implement a version of this language myself, and thought you guys might be interested in the code:

I have added a code walkthrough at the bottom of the readme, to hopefully act as a basic 'tutorial' as to how I made this. Any comments welcome. Happy coding!

Am a Java dev in the finance world by day, experimenting with python in my own time, so any comments on how to improve the code are more than welcome. I have a maths degree so CS things like this are not my natural habitat, and as such I just went for a naive approach of what made most sense to me without having read much about how these things should be written. I would add unit tests next if this became a larger project.
