Tic Tac Toe game in Python

Tic Tac Toe game in Python using Tkinter for a graphical user interface (GUI)

In this article, print_board function is used to display the Tic-Tac-Toe board with beautiful formatting using Unicode characters. The players can enter their moves by specifying a position from 1 to 9. The game checks for wins and ties and switches players after each turn.


import tkinter as tk
from tkinter import messagebox

class TicTacToeGUI:
    def __init__(self):
        self.current_player = "X"
        self.board = [" " for _ in range(9)]

    def create_gui(self):
        self.root = tk.Tk()

        self.buttons = []
        for i in range(3):
            row = []
            for j in range(3):
                button = tk.Button(self.root, text=" ", font=("Helvetica", 20, "bold"), width=6, height=3,
                                   command=lambda i=i, j=j: self.make_move(i, j))
                button.grid(row=i, column=j, padx=5, pady=5)

    def make_move(self, row, col):
        if self.board[row * 3 + col] == " ":
            self.board[row * 3 + col] = self.current_player

            if self.check_win():
                messagebox.showinfo("Game Over", "Player {} wins!".format(self.current_player))
            elif " " not in self.board:
                messagebox.showinfo("Game Over", "It's a tie!")
                self.current_player = "O" if self.current_player == "X" else "X"

    def check_win(self):
        win_patterns = [[0, 1, 2], [3, 4, 5], [6, 7, 8],  # rows
                        [0, 3, 6], [1, 4, 7], [2, 5, 8],  # columns
                        [0, 4, 8], [2, 4, 6]]  # diagonals

        for pattern in win_patterns:
            if self.board[pattern[0]] == self.board[pattern[1]] == self.board[pattern[2]] != " ":
                return True
        return False

    def reset_game(self):
        self.current_player = "X"
        self.board = [" " for _ in range(9)]

        for i in range(3):
            for j in range(3):
                self.buttons[i][j].config(text=" ", state=tk.NORMAL)

    def start_game(self):

if __name__ == "__main__":
    game = TicTacToeGUI()

This code creates a GUI for the Tic-Tac-Toe game using the Tkinter library. The game window consists of 9 buttons arranged in a 3×3 grid. Each button represents a cell on the Tic-Tac-Toe board.

Working Video

When a player clicks on a button, the make_move function is called to update the game state and display the current player’s symbol on the button. The game checks for a win or a tie after each move, and if either condition is met, a message box is displayed with the game result. Players can then reset the game and start a new round.

  • To run the code, ensure that you have Tkinter installed (it comes pre-installed with most Python distributions).
  • Then, execute the Python script and a window with the Tic-Tac-Toe game will appear.
  • You can take turns making moves by clicking on the buttons, and the game will display the winner or declare a tie when appropriate.

Note: This code represents a simple implementation of the game and does not include advanced features such as computer AI for playing against the computer.
