I didn't know what sort of title to give this post. I'm a new to python, and I'm 4 weeks into my first class. I wrote a Tic Tac Toe program with an AI, but the AI is weird. It behaves differently at my home PC than at my school PC. At school, the program just crashes once it become's the computers turn for a move. It doesn't even draw the boxes. At home the computer just doesn't move. My home computer is significantly better than my school computer by the way. Also it's running Windows 10 TP vs. Windows 7 at school. I showed my teacher and he couldn't tell me the problem. This is my code. Sorry it's all one file and it's all the code I have because I have no idea where the problem is. Also I'm using PyProcessing which is basically a python IDE that provides some simple ways for graphics. The setup() function runs automatically at the beginning and so does draw() but I'm not sure when or what causes the draw() function to run.
