Python implements simple tic-tac-toe game

Tic-tac-toe, the English name is Tic-Tac-Toe, is a kind of renju game played on a 3*3 grid. It is similar to Gobang. Because the board generally does not have a border, the grid lines are arranged in tic-tac-toe so it is named. The only tools needed for the game are paper and pen, and then two players representing O and X take turns to leave marks in the grid (generally, the first player is X), any three marks forming a straight line, it is a win .

The difficulty of the game is how to judge that the connection is a line; horizontal, vertical and oblique directions;
