Bored!! Lets Create Tic Tac Toe In Python

 

Steps to create tic tac toe:- 

1. design a board
2. print board everytime you enter your input
3. assign current user 'X' or 'O'
4. flip between players so that both gets chance to play
5.  assign the input to the input position you provided between 1-9
6. validate your input such that it falls between 1 - 9 and it doesnt override the previous input
7. Check whether the game is tie if not display the winner and exit.

Looks simple now just dive into my below code and you will understand it easily.

theBoard = ['-', '-', '-',
            '-', '-', '-',
            '-', '-', '-']
current_player = 'X'
filled_board = True
valid_inputs = ['1', '2', '3', '4', '5', '6', '7', '8', '9']


def print_board(board):
    print(board[0] + ' | ' + board[1] + ' | ' + board[2])
    print(board[3] + ' | ' + board[4] + ' | ' + board[5])
    print(board[6] + ' | ' + board[7] + ' | ' + board[8])


def play_game(board):
    print_board(theBoard)
    global filled_board
    global valid_inputs

    while filled_board:
        pos = input(f'enter your choice player "{current_player}" between 1-9 :: ')
        while pos not in valid_inputs or board[int(pos) - 1] != '-':
            pos = input(
                f'Invalid Input or position already filled!! please enter valid choice player "{current_player}" between 1-9 :: ')
        else:
            position = int(pos) - 1
        board[position] = current_player
        flip_player(current_player)

        if '-' not in theBoard:
            filled_board = False
        print_board(board)

        winner_result(board)


def flip_player(player):
    global current_player
    if player == 'O':
        current_player = 'X'
    elif player == 'X':
        current_player = 'O'


def winner_result(board):
    global filled_board
    winner = ''
    if board[0] != '-' and board[0] == board[1] == board[2]:
        winner = board[0]
    elif board[3] != '-' and board[3] == board[4] == board[5]:
        winner = board[3]
    elif board[6] != '-' and board[6] == board[7] == board[8]:
        winner = board[6]
    elif board[0] != '-' and board[0] == board[3] == board[6]:
        winner = board[0]
    elif board[1] != '-' and board[1] == board[4] == board[7]:
        winner = board[1]
    elif board[2] != '-' and board[2] == board[5] == board[8]:
        winner = board[2]
    elif board[0] != '-' and board[0] == board[4] == board[8]:
        winner = board[0]
    elif board[2] != '-' and board[2] == board[4] == board[6]:
        winner = board[2]
    if winner == '' and not filled_board:
        print("Game Over Its a tie!!")
        exit(1)
    elif winner != '' and filled_board:
        print(f'Game Over {winner} Wins!!')
        exit(1)
