python井字棋代码

以下是一个简单的 Python 井字棋代码：

def print_board(board):
    print(f'{board[0]} | {board[1]} | {board[2]}')
    print('-' * 9)
    print(f'{board[3]} | {board[4]} | {board[5]}')
    print('-' * 9)
    print(f'{board[6]} | {board[7]} | {board[8]}')

def play_game():
    board = [' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ']
    player = 'X'
    print_board(board)
    while True:
        move = input(f'Player {player}, enter a position number (1-9): ')
        move = int(move) - 1
        if board[move] == ' ':
            board[move] = player
            print_board(board)
            if check_winner(board, player):
                print(f'Player {player} wins!')
                break
            if check_tie(board):
                print('It\'s a tie!')
                break
            player = 'O' if player == 'X' else 'X'
        else:
            print('That position is already taken. Please try again.')

def check_winner(board, player):
    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 board[win[0]] == board[win[1]] == board[win[2]] == player:
            return True
    return False

def check_tie(board):
    return ' ' not in board

play_game()

这个代码实现了一个基本的井字棋游戏，玩家通过输入数字来选择下棋的位置。代码使用一个列表来存储棋盘，并且在每次玩家下完棋后检查是否有胜者或者是否平局。
