用python写一个五子棋代码

好的，以下是一个五子棋代码的示例，使用Python实现：

# 定义一个棋盘类
class Board:
    def __init__(self):
        self.width = 15
        self.height = 15
        self.board = [[' ' for y in range(self.height)] for x in range(self.width)]

    def print_board(self):
        print('    1   2   3   4   5   6   7   8   9  10  11  12  13  14  15')
        print('  +' + '---+'*15)
        for y in range(self.height):
            print(chr(y+65) + ' |', end='')
            for x in range(self.width):
                print(f' {self.board[x][y]} |', end='')
            print()
            print('  +' + '---+'*15)

    def place(self, x, y, piece):
        self.board[x][y] = piece

    def get(self, x, y):
        return self.board[x][y]

    def is_valid_move(self, x, y):
        return x >= 0 and x < self.width and y >= 0 and y < self.height and self.board[x][y] == ' '

# 定义一个游戏类
class Game:
    def __init__(self):
        self.board = Board()
        self.players = ['X', 'O']
        self.current_player = self.players[0]

    def switch_player(self):
        if self.current_player == self.players[0]:
            self.current_player = self.players[1]
        else:
            self.current_player = self.players[0]

    def play(self):
        while True:
            self.board.print_board()
            move = input(f'{self.current_player}, enter your move (e.g. A1): ')
            if len(move) != 2 or not move[0].isalpha() or not move[1].isdigit():
                print('Invalid move, please try again.')
                continue
            x = ord(move[0].upper()) - 65
            y = int(move[1]) - 1
            if not self.board.is_valid_move(x, y):
                print('Invalid move, please try again.')
                continue
            self.board.place(x, y, self.current_player)
            if self.is_winner():
                self.board.print_board()
                print(f'{self.current_player} wins!')
                break
            self.switch_player()

    def is_winner(self):
        for y in range(self.board.height):
            for x in range(self.board.width):
                if x + 4 < self.board.width and \
                   self.board.get(x,y) == self.current_player and \
                   self.board.get(x+1,y) == self.current_player and \
                   self.board.get(x+2,y) == self.current_player and \
                   self.board.get(x+3,y) == self.current_player and \
                   self.board.get(x+4,y) == self.current_player:
                    return True
                elif y + 4 < self.board.height and \
                     self.board.get(x,y) == self.current_player and \
                     self.board.get(x,y+1) == self.current_player and \

                     self.board.get(x+4,y+4) == self.current_player:
                    return True
                elif x + 4 < self.board.width and y - 4 >= 0 and \
                     self.board.get(x,y) == self.current_player and \
                     self.board.get(x+1,y-1) == self.current_player and \
                     self.board.get(x+2,y-2) == self.current_player and \
                     self.board.get(x+3,y-3) == self.current_player and \

                    return True
        return False

# 创建游戏对象并开始游戏
game = Game()
game.play()

请注意，这只是一个示例代码，可能需要进行更多的测试和改进，并根据需要进行自定义。
