Introduction

I made this game as a challenge to create the smallest possible code for a Tic Tac Toe game in Python. The requirements on the game are as follows:

• A "nice" playing experience (ability to get user input and print the board after every move)
• Handling wrong input data without crashing.
• Having an unbeatable AI as opponent.
• The ability to play again or exit after game is over

Setup

You can run the desired game version in your IDE or from the console, no extra modules or installations needed.

How to play

When you play you are asked to input a number, which corresponds to a square as given in below picture. You can set the parameter user_turn to False if AI should play first.

[1, 2, 3]
[4, 5, 6]
[7, 8, 9]

Results

The results you can see in the files ending with '_compressed'. I also included well commented and PEP8 friendly versions in the repository with the suffix '_commented' to be able to understand what is going on :)
