Checkers seems popular around here. What if I want to change "white" to 
"red," as red and black is a common color scheme for checkers. Do I 
change a single constant variable or replace all the occurrences in the 
files?

Some of these constants are shortcuts. Instead of writing slice(0, 16) 
or slice(48, 64), and getting the two confused, I write 
const['board_bottom'] or const['board_top'], respectively, when I want 
to pull the correct set of positions from coordinates list.

I did that at first, made it into a dictionary class and added 
ConfigParser to the mix. I had a lot of fun putting that one together. 
However, as I refactor my code further as I learn new things, it will 
probably get changed or removed. Being a research project, I'm willing 
to dive into every rabbit hole that I come across to learn Python properly.

Thank you,
