五子棋游戏代码：Python实现

以下是一个简单的五子棋代码，使用 Python 语言编写：

import numpy as np

# 定义棋盘大小
BOARD_SIZE = 15

# 定义黑白棋子的常量
EMPTY = 0
WHITE = 1
BLACK = 2

class Game:
    def __init__(self):
        # 初始化棋盘
        self.board = np.zeros((BOARD_SIZE, BOARD_SIZE))
        # 初始化当前落子方
        self.current_player = BLACK

    def play(self, x, y):
        # 落子
        self.board[x][y] = self.current_player
        # 判断是否胜利
        if self.is_win(x, y):
            print('Player', self.current_player, 'wins!')
            return
        # 切换落子方
        self.current_player = BLACK if self.current_player == WHITE else WHITE

    def is_win(self, x, y):
        # 判断横向是否有五子相连
        if (self.board[x][y] == self.board[x-1][y] == self.board[x-2][y] == self.board[x-3][y] == self.board[x-4][y] == self.current_player) or \
