用python写一个五子棋

好的，下面是用 Python 写的五子棋游戏代码：

import numpy as np

# 定义棋盘大小
BOARD_SIZE = 15

class Board(object):
    def __init__(self):
        self.board = np.zeros((BOARD_SIZE, BOARD_SIZE))
        self.current_player = 1
        self.game_over = False

    # 判断棋子是否在棋盘内
    def in_board(self, x, y):
        return x >= 0 and x < BOARD_SIZE and y >= 0 and y < BOARD_SIZE

    # 判断该位置是否为空
    def is_empty(self, x, y):
        return self.board[x][y] == 0

    # 落子
    def move(self, x, y):
        if not self.in_board(x, y):
            print('该位置不在棋盘内，请重新落子！')
            return False
        if not self.is_empty(x, y):
            print('该位置已经有棋子，请重新落子！')
            return False
        self.board[x][y] = self.current_player
        self.current_player = 3 - self.current_player
        return True

    # 判断是否有五子连珠
    def check_win(self, x, y):
        directions = ((0, 1), (1, 0), (1, 1), (-1, 1))
        for dx, dy in directions:
            count = 1
            for i in range(1, 5):
                new_x, new_y = x + i * dx, y + i * dy
                if self.in_board(new_x, new_y) and self.board[new_x][new_y] == self.board[x][y]:
                    count += 1
                else:
                    break
            for i in range(1, 5):
                new_x, new_y = x - i * dx, y - i * dy
                if self.in_board(new_x, new_y) and self.board[new_x][new_y] == self.board[x][y]:
                    count += 1
                else:
                    break
            if count >= 5:
                return True
        return False

    # 判断游戏是否结束
    def is_game_over(self):
        for x in range(BOARD_SIZE):
            for y in range(BOARD_SIZE):
                if self.board[x][y] == 0:
                    continue
                if self.check_win(x, y):
                    self.game_over = True
                    return True
        return False

    # 打印棋盘
    def print_board(self):
        print('  ', end='')
        for i in range(BOARD_SIZE):
            print(chr(ord('a') + i), end=' ')
        print()
        for i in range(BOARD_SIZE):
            print('%2d' % (i + 1), end=' ')
            for j in range(BOARD_SIZE):
                if self.board[i][j] == 1:
                    print('●', end=' ')
                elif self.board[i][j] == 2:
                    print('○', end=' ')
                else:
                    print('+', end=' ')
            print()

# 游戏主函数
def main():
    board = Board()
    while not board.is_game_over():
        board.print_board()
        if board.current_player == 1:
            print('轮到黑方下棋（●）：', end='')
        else:
            print('轮到白方下棋（○）：', end='')
        move = input()
        x, y = ord(move[0]) - ord('a'), int(move[1:]) - 1
        if board.move(x, y):
            print()
        else:
            print('请重新输入落子位置！')
    board.print_board()
    if board.current_player == 1:
        print('白方（○）获胜！')
    else:
        print('黑方（●）获胜！')

if __name__ == '__main__':
    main()

这个程序使用了 numpy 库来实现二维棋盘的数据存储和处理，代码中实现了落子、判断是否有五子连珠、判断游戏是否结束和打印棋盘等功能。
