python人机交互的井字棋用类

以下是使用类实现Python人机交互的井字棋的示例代码：

class TicTacToe:
    def __init__(self):
        self.board = [' ' for _ in range(9)] # 初始化棋盘为空格
        self.current_winner = None # 当前胜者

    def print_board(self):
        # 打印棋盘
        for row in [self.board[i*3:(i+1)*3] for i in range(3)]:
            print('| ' + ' | '.join(row) + ' |')

    @staticmethod
    def print_board_nums():
        # 打印棋盘的数字编号
        number_board = [[str(i) for i in range(j*3, (j+1)*3)] for j in range(3)]
        for row in number_board:
            print('| ' + ' | '.join(row) + ' |')

    def available_moves(self):
        # 返回当前棋盘上的空格
        return [i for i, spot in enumerate(self.board) if spot == ' ']
    def empty_squares(self):
        # 返回当前棋盘上的空格
        return ' ' in self.board

    def num_empty_squares(self):
        # 返回当前棋盘上的空格数量
        return self.board.count(' ')

    def make_move(self, square, letter):
        # 在指定位置落子
        if self.board[square] == ' ':
            self.board[square] = letter
            if self.winner(square, letter):
                self.current_winner = letter
            return True
        return False

    def winner(self, square, letter):
        # 判断是否有胜者
        row_ind = square // 3
        row = self.board[row_ind*3 : (row_ind+1)*3]

            return True

            diagonal1 = [self.board[i] for i in [0, 4, 8]]
            if all([spot == letter for spot in diagonal1]):
                return True
            diagonal2 = [self.board[i] for i in [2, 4, 6]]
            if all([spot == letter for spot in diagonal2]):
                return True

        return False

def play(game, x_player, o_player, print_game=True):
    # 开始游戏
    if print_game:
        game.print_board_nums()

    letter = 'X' # X先手
    while game.empty_squares():
        if letter == 'O':
            square = o_player.get_move(game)
        else:
            square = x_player.get_move(game)

        if game.make_move(square, letter):
            if print_game:
                print(letter + f' makes a move to square {square}')
                game.print_board()
                print('')

            if game.current_winner:
                if print_game:
                    print(letter + ' wins!')
                return letter

            letter = 'O' if letter == 'X' else 'X'

    if print_game:
        print('It\'s a tie!')

if __name__ == '__main__':
    x_player = HumanPlayer('X')
    o_player = RandomComputerPlayer('O')
    t = TicTacToe()
    play(t, x_player, o_player, print_game=True)
