Tic Tac Toe Python Code
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] != ' '):

else:
print("Player 2's chance")
Mark = 'O'
choice = int(input("choose a position between [1-9]: "))
if(CheckPosition(choice)):
board[choice] = Mark

if(Game==Draw):
print("Game Draw")
