Tic Tac Toe (part 3)

In part 1 of this project, you created the functions necessary to print a game board. In part 2 you added the game state and player input. Now, it’s time to add the final touch: winning! 👑

Your program must follow these specifications:

• Add new code to the tic_tac_toe.py file

• Create a new function called check_winner (see details below)

  • Will return one of these values: 'X', 'O', 'tie', or None

• In the main game loop, call the function check_winner and do the following with the results:

  • If 'X' or 'O', stop looping and announce the winner
  • If 'tie', stop looping and announce that the game was a “cat game”
  • If None, continue the loop as normal

• When a player gets three pieces in a row (horizontally, vertically, or diagonally) the game loop must end and the winner must be announced

• If all cells on the board are filled with pieces (but no player has won) the game loop must end and it must be announced that it was a “cat game” (draw, tie)

Checking the Winner

Your new function check_winner must check the current game state (in board variable) and do the following:

• If a player gets three pieces in a row (horizontally, vertically, or diagonally) return that player’s piece ('X' or 'O')
• If all cells on the board are filled with pieces (but no player has won) return 'tie'
• Otherwise, return None

Thare are several ways that you can check whether a player has three pieces in a row, it doesn’t really matter how you do it. The important thing is that a player can win, lose, or tie to end the game.

Just make sure to test your code before submitting!
