Question

这是家庭作业 当用户说他们不想再玩时，我试图让程序破解，但我无法让它工作。该程序告诉用户再次尝试但保持相同的单词并且不会中断。我的循环有问题吗？如果没有，问题是什么，我该如何解决？

Answer 1

我认为您的问题是您以递归方式调用playGame()。当你休息时，你正在回到循环中，可能选择了不同的单词。有几种方法可以处理它。一个是当你想退出时打电话给sys.exit()。第二种方法是传递一个变量，知道你需要退出，并在while循环中检查该变量。或者甚至更好，采取逻辑来决定你是否应该在循环之外再次玩。下面是一个简单的例子。只需用break语句替换您的代码块即可结束游戏，该游戏将下拉到主游戏循环中，如下所示。

while (True):
    playGame()
    replay=str(input(""" Want to try again? Enter yes or no"""))
    replay=replay.lower();   # This line converts to lower case, removing some checks.
    if replay=='no' or or replay=='n' or replay=='this game sucked':
          print("Well, have a nice day then")
          break

Answer 2

我认为休息只会从最内层循环中消失。请参阅：http://docs.python.org/2/reference/simple_stmts.html#break

如果你想退出该计划，我相信你所寻找的是sys.exit()。

Answer 3

使用sys.exit()或raise SystemExit

... 
print("You did not get the word. Try again!")
replay=str(input(""" Want to try again? Enter yes or no"""))
if replay=='yes' or replay=='YES' or replay=='Yes':
    playGame()
if replay=='no' or replay=='NO' or replay=='n' or replay=='this game sucked':
    print("Well, have a nice day then")
    sys.exit()
    #raise SystemExit
...

这将完全结束该计划。
