Python Code to build a Tic-tac-toe Game

 Tic Tac Toe Python Code

Tic Tac Toe Python Game

In an earlier post, we have introduced the Tic-Tac-Toe Game ready for you. In this post, we will make the game in python.

Code 1:

In this game, you will play with your friend, and you decide who chooses X and who goes with O. Players play respectively (one after another). The filled square cannot be filled again or changed. The one who places 3 respective marks first (horizontally, vertically, or diagonally) wins the game.

The Code:

import os    

import time    

   

board = [' ',' ',' ',' ',' ',' ',' ',' ',' ',' ']    

player = 1    

   

########win Flags##########    

Win = 1    

Draw = -1    

Running = 0    

Stop = 1    

Game = Running    

Mark = 'X'    

   

#This Function Draws Game Board    

def DrawBoard():    

    print(" %c | %c | %c " % (board[1],board[2],board[3]))

    print("___|___|___")

    print(" %c | %c | %c " % (board[4],board[5],board[6]))    

    print("___|___|___")    

    print(" %c | %c | %c " % (board[7],board[8],board[9]))    

    print("   |   |   ")    

   

#This Function Checks position is empty or not    

def CheckPosition(x):    

    if(board[x] == ' '):    

        return True    

    else:    

        return False    

   

#This Function Checks player has won or not    

def CheckWin():    

    global Game    

    #Horizontal winning condition    

    if(board[1] == board[2] and board[2] == board[3] and board[1] != ' '):    

        Game = Win    

    elif(board[4] == board[5] and board[5] == board[6] and board[4] != ' '):    

        Game = Win    

    elif(board[7] == board[8] and board[8] == board[9] and board[7] != ' '):    

        Game = Win    

    #Vertical Winning Condition

        Game = Win

        Game=Win

    #Diagonal Winning Condition

        Game = Win

         and board[4]!=' ' and board[5]!=' '

         and board[6]!=' ' and board[7]!=' '

         and board[8]!=' ' and board[9]!=' '):

        Game=Draw

    else:

        Game=Running

print("Tic-Tac-Toe Game is running")    

print("Player 1 [X] --- Player 2 [O]\n")

print()

print()

print("Please Wait...")

time.sleep(3)

while(Game == Running):

    os.system('cls')

    DrawBoard()

    if(player % 2 != 0):

        print("Player 1's chance")

        Mark = 'X'

    else:

        print("Player 2's chance")

        Mark = 'O'

    choice = int(input("choose a position between [1-9]: "))

    if(CheckPosition(choice)):

        board[choice] = Mark

        player+=1

        CheckWin()
