當用戶用完猜測

Question

THIS IS HOMEWORK 我試圖讓該程序，當用戶說，他們不想再玩了打破的，我不能讓我的劊子手計劃打破，但我無法讓它工作。該程序告訴用戶再次嘗試，但保持相同的單詞，不會中斷。我的循環有什麼問題嗎？如果不是，那麼問題是什麼，我該如何解決？

在此先感謝

Answer 1

我覺得break只能從最內層循環中跳出來。見：http://docs.python.org/2/reference/simple_stmts.html#break

我相信你在找什麼是sys.exit()如果你想退出程序。

Answer 2

我認爲你的問題是，你是遞歸調用playGame()。當你休息時，你會重新回到循環中，可能會選擇一個不同的單詞。有幾種方法可以處理它。當你想要退出時，你可以撥打sys.exit()。第二種方法是通過傳遞一個變量來知道你需要退出，並在while循環中檢查該變量。或者更好的是，根據邏輯來決定是否應該在循環之外再次進行比賽。下面是一個簡單的例子。只需用break語句代替您的代碼塊即可結束遊戲，遊戲將下降到主遊戲循環中，如下所述。

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 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 
... 

這將徹底結束程序。
