Hi Ni'Yana,
Here's a little transcript of what I'd do if I were to take a testing
approach to the problem.

Let's say that we start with a fresh board. Imagine that we've just
created a fresh ReversiGameLogic.
What does the board look like? Let's look at the state in the initializer.

Hello all,
I'm new to python and a bit of a weekend-warrior programmer (guitar
teacher by trade), so there are plenty of computer sciencey concepts
that I haven't grasped yet, and I think I'm bumping up against those now.
Read from separate csv files, I have something like
a=[['bass',9],[
I am very new to Comp Science and am still learning.
I have attached the programs needed for testing to show that I am testing my
code as well as the instructions provided for my project.
Please help me out!

Hi,
This is mostly a distant footnote to Doug Basberg's original
question, which I believe is largely answered at this point.
Albert-Jan Roskum, Alan Gauld and Steven D'Aprano were asking about
signals and how they are handled (in Un*xen). I am trying to
address that.
Yeah, I know you c
