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

    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

Added another version with colors and more refactoring

added draw condition in case no players wins

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

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