1. 实验内容

利用pygame编写扫雷的小游戏，包含基本的游戏界面和胜负判定。

2. 游戏运行过程

3. 源代码

os.environ['SDL_VIDEO_WINDOW_POS'] = "%d,%d" % (100, 100)

# 游戏窗口大小
WINDOW_WIDTH = 300
WINDOW_HEIGHT = 300

# 游戏格子大小
CELL_SIZE = 20

# 雷的数量
NUM_MINES = 20

# 颜色定义
WHITE = (255, 255, 255)
BLACK = (0, 0, 0)

# 初始化pygame
pygame.init()

# 创建游戏窗口
