python五子棋代码

以下是一个简单的 Python 五子棋代码实现，包含了基本的游戏逻辑，但没有图形界面。

# 定义棋盘大小
BOARD_SIZE = 15

# 定义棋子类型
EMPTY = 0
BLACK = 1
WHITE = 2

class Board:
    def __init__(self):
        self.board = [[EMPTY] * BOARD_SIZE for _ in range(BOARD_SIZE)]
        self.current_player = BLACK

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

    def put(self, x, y):
        if self.get(x, y) != EMPTY:
            raise ValueError("该位置已经有棋子了！")
        self.board[x][y] = self.current_player
        self.current_player = WHITE if self.current_player == BLACK else BLACK

    def is_full(self):
        for i in range(BOARD_SIZE):
            for j in range(BOARD_SIZE):
                if self.get(i, j) == EMPTY:
                    return False
        return True

    def check_win(self, x, y):
        directions = [(1, 0), (0, 1), (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 new_x < 0 or new_x >= BOARD_SIZE or new_y < 0 or new_y >= BOARD_SIZE:
                    break
                if self.get(new_x, new_y) == self.current_player:
                    count += 1
                else:
                    break
            for i in range(1, 5):
                new_x, new_y = x - i * dx, y - i * dy
                if new_x < 0 or new_x >= BOARD_SIZE or new_y < 0 or new_y >= BOARD_SIZE:
                    break
                if self.get(new_x, new_y) == self.current_player:
                    count += 1
                else:
                    break
            if count >= 5:
                return True
        return False

    def print_board(self):
        for i in range(BOARD_SIZE):
            for j in range(BOARD_SIZE):
                if self.get(i, j) == EMPTY:
                    print(".", end=" ")
                elif self.get(i, j) == BLACK:
                    print("X", end=" ")
                else:
                    print("O", end=" ")
            print()

if __name__ == "__main__":
    board = Board()
    while not board.is_full():
        board.print_board()
        x, y = map(int, input("请下棋（例如：3 5）：").split())
        try:
            board.put(x, y)
            if board.check_win(x, y):
                board.print_board()
                print("恭喜，玩家 {} 获胜！".format("黑棋" if board.current_player == WHITE else "白棋"))
                break
        except ValueError as e:
            print(str(e))
    else:
        board.print_board()
        print("平局！")

这个代码实现了一个 `Board` 类，包含了下棋、判断胜负、输出棋盘等方法。在 `__main__` 函数中，通过不断循环，让用户输入坐标来下棋，直到棋盘填满或者某一方胜利。
