Hello Evilzone! First time poster, short time lurker here. I have recently started digging into programming and went with Python! Just for educational purposes on my behalf, I want to post this Tic Tac Toe game I have been working on! I am open to any suggestions to improve what may seem like redundant code. Thanks in advance!
