Hi there! And welcome to my Tic Tac Toe game, made with tkinter.
Here's how to play Tic-Tac-Toe! As you can see, the game is played on a grid that is 3 squares by 3 squares.
1. The player that starts is X, and the other person is O. You and another player take turns placing X or O into a square.
2. The first player to get all 3 marks in a row (horizontally, vertically or diagonally) wins the game.
3. When all the squares are filled and no one has won, the game ends in a tie. AND THAT'S IT! Have fun playing!
And press reset to play again!""",

This is my code so far, when I run it and play the tic-tac-toe game it works well. However, after I finish a game with a winner and the new window pops up with 'player X' or 'player o' wins, I am still able to press the buttons - I'd like it so that the buttons can't be pressed anymore, but I'm not sure how - i know that the button.destroy() function might work but I dont know how to do it for the remaining few. If I could get some help on this that could be great! Thanks.
You can just introduce a global variable, let's say game_active, to track whether the game is ongoing. This will be True when the game starts and should be set to False when someone wins or there is a tie.
I modified the button_click function to check the state of game_active before proceeding with its logic. If game_active is False, the function should return immediately.
Set game_active to False in the check_winner function when there is a winner.
Obviously reset game_active to True every time a new game starts.
Example:
game_active = True
def button_click(row, col, button, parent): global o_Turn, game_active
