我正在尝试使用python构建一个简单的Tic Tac Toe游戏，现在几乎就在那里，除非游戏在每次打结时崩溃
所以当它是平局时，点击的最后一个空方块不会像其他人那样改变颜色，并且窗口冻结，点击被禁用....我不知道原因是
我的整个代码在这里：

答案 0 :(得分：2)
尝试替换
def pc_move(self):
m = True
while m:
使用
while not self.board_full():
然后将m设置回假break，而不是。{/ p>
您的代码无效的原因是因为如果if pc_move in self.possible_moves():返回false，则运行：
else:
continue
直到时间结束。
