这次我们基于 pygame 来做一个扫雷，我所有的代码都是基于 python 3.6 的。
下面将一下我的实现逻辑
首先，如何表示雷和非雷，一开始有好多状态，后来一想，干脆就做个类吧。
class BlockStatus(Enum):normal = 1# 未点opened = 2# 已点mine = 3# 雷flag = 4# 标记雷ask = 5 # 标记问号bomb = 6# 踩中雷hint = 7# 被双击周围double = 8# 正在被鼠标左右键双击class Mine:def __init__(self, x, y, value=0):self._x = xself._y = yself._value = 0self._around_mine_count = -1self._status = BlockStatus.normalself.set_value(value)def __repr__(self):return str(self._value)# return f'({self._x},{self._y})={self._value}, status={self.status}'def get_x(self):return self._xdef set_x(self, x):self._x = xx = property(fget=get_x, fset=set_x)def get_y(self):return self._ydef set_y(self, y):self._y = yy = property(fget=get_y, fset=set_y)def get_value(self):return self._valuedef set_value(self, value):if value:self._value = 1else:self._value = 0value = property(fget=get_value, fset=set_value, doc='0:非地雷 1:雷')def get_around_mine_count(self):return self._around_mine_countdef set_around_mine_count(self, around_mine_count):self._around_mine_count = around_mine_countaround_mine_count = property(fget=get_around_mine_count, fset=set_around_mine_count, doc='四周地雷数量')def get_status(self):return self._statusdef set_status(self, value):self._status = valuestatus = property(fget=get_status, fset=set_status, doc='BlockStatus')布雷就很简单了，随机取99个数，从上往下顺序排
class MineBlock:def __init__(self):self._block = [[Mine(i, j) for i in range(BLOCK_WIDTH)] for j in range(BLOCK_HEIGHT)]# 埋雷for i in random.sample(range(BLOCK_WIDTH * BLOCK_HEIGHT), MINE_COUNT):self._block[i // BLOCK_WIDTH][i % BLOCK_WIDTH].value = 1点击一个格子的时候，只要根据点击的坐标，找到对应的 Mine，看它的值是多少，就知道有没有踩中雷
如果没踩中雷的话，要计算周边8个位置中有几个雷，以便显示对应的数字
如果周边有雷，那么显示数字，这个简单，可是如果周边没有雷，那就要显示一片区域，直到有雷出现
这个计算其实也容易，用递归就可以了，如果计算出周围的雷数为0，则递归计算周边8个位置的四周雷数，直到雷数不为0
