我如何打破2个循环？（Python）

Question

必须有更好的方法来做这件事。。。有什么想法吗？这是CS1的基本21点游戏。在

有两件事困扰着我：

1. 我怎样才能两次跳出这个循环？例：庄家赢了，然后问“留下还是打？”，因为它仍然在玩家的回合/循环中。在
2. 休息时间似乎很粗糙。有很多复制粘贴的代码。在

谢谢！感谢任何帮助。在

在外循环的开始处创建一个标志为FALSE。。。然后在内部循环中，当需要中断2个循环时，将其设置为真，现在您将中断内部循环，并检查外部循环中的标志，如果为真，则也将中断此（外部循环）的标志。在

while ...:
 flag = 0
   while ...:
     #  point where you want 2 loops to break
     flag = 1
     break
 # break out of this too :P
 if flag == 1:
  break
