Hi all,
I have written a Python Tic Tac Toe game with functions for 2 players on a shared keyboard. I am interested in feedback. It works well, but I am interested in proper scoping of variables ? Have I used functions in a correct way and anything else is highly appreciated. I am learning how to code, however I want to do it in the correct way. I am not up to classes yet. That will be my next project.
Thank you
Joris
