Code for the tic tac toe game we created in this video: https://youtu.be/E8fmDDtaHLU on CodeWithHarry channel on YouTube

Tic-Tac-Toe.py

def sum(a, b, c ):
    return a + b + c

def printBoard(xState, zState):
    zero = 'X' if xState[0] else ('O' if zState[0] else 0)
    one = 'X' if xState[1] else ('O' if zState[1] else 1)
    two = 'X' if xState[2] else ('O' if zState[2] else 2)
    three = 'X' if xState[3] else ('O' if zState[3] else 3)
    four = 'X' if xState[4] else ('O' if zState[4] else 4)

def checkWin(xState, zState):
    wins = [[0, 1, 2], [3, 4, 5], [6, 7, 8], [0, 3, 6], [1, 4, 7], [2, 5, 8], [0, 4, 8], [2, 4, 6]]
    for win in wins:
        if(sum(xState[win[0]], xState[win[1]], xState[win[2]]) == 3):
            print("X Won the match")
            return 1
        if(sum(zState[win[0]], zState[win[1]], zState[win[2]]) == 3):
            print("O Won the match")
            return 0
    return -1
    
if __name__ == "__main__":
    xState = [0, 0, 0, 0, 0, 0, 0, 0, 0]
    zState = [0, 0, 0, 0, 0, 0, 0, 0, 0]
    turn = 1 # 1 for X and 0 for O
    print("Welcome to Tic Tac Toe")
    while(True):
        printBoard(xState, zState)
        if(turn == 1):
            print("X's Chance")
            value = int(input("Please enter a value: "))
            xState[value] = 1
        else:
            print("O's Chance")
            value = int(input("Please enter a value: "))
            zState[value] = 1
        cwin = checkWin(xState, zState)
        if(cwin != -1):
            print("Match over")
            break
        
        turn = 1 - turn

There are some of glitches in the given code which i could find:

1. It goes to infinity when no match is made.
2. It doesn't shows the the final board and declare directly the winning team.

Sir i watch many videos in your channel but dnt know why only this video disappointed me to learn

but you are still best >>

i dont find i easy to understand and learn like other video of yours

great work harray vaia

Run code

you did great harry vai love from NEPAL

Please code the same game but the opponent should be a computer. So, human vs computer.

Thank you harry bhai :)

Hi harry, can you play tic-tac-toe with AI ?
Please code the same game but the opponent should be a computer. So, human vs computer.

Major Update

I modified your code and included some major updates like save/load feature, AI opponent, etc. This is currently under development but soon this update will be available from my forked repo of this repo.
