At the risk of belabouring this thread, I wanted to update you with
developments on my earlier requests for input and since you all so
graciously contributed something to helping me, I wanted to share where
it is at (to date).
I utilised Magnus's idea regarding turning the rock, paper, scissors
combination into a dictionary, and calling the key/value pair to
ascertain which wins.
I also wanted to allow the user to keep the game going rather than just
play once and have to press F5 again to start it off, which is why I
created the game as a module itself that can just be called.
Finally, I wanted to provide a little more feedback to the user - hence
all the stuff about the round summary.
I was hoping that I might be able to carry a round winner's total over
from one game to the next to give a series summary upon quitting, but
haven't figured out how to do that yet.
Anyway, have attached the code, and would naturally welcome comments.
It is probably too many lines for what the program actually does, so if
you have any ideas how parsimony can be achieved, please share them with
me, but I'd also appreciate it if you could explain what it is that you
are actually doing too - that would aid my learning.

Thanks folks.
Kind regards
Andrew
