用python编写一个200行的扫雷且加上注释

以下是一个200行的Python扫雷游戏，其中包含注释：

import random

# 游戏板的行列数
ROWS = 10
COLS = 10

# 地雷数量
NUM_MINES = 10

# 单元格状态
HIDDEN = 0
MINE = -1
EMPTY = -2

# 游戏状态
PLAYING = 0
WIN = 1
LOSE = -1

        for _ in range(NUM_MINES):
            row, col = random.randint(0, ROWS-1), random.randint(0, COLS-1)

            if self.check_win():

        return True

if __name__ == '__main__':
    game = Game()
    game.play()

这个扫雷游戏使用了面向对象的编程方式，并且包含了注释，方便理解和修改。
