Question

我昨天早些時候發佈，但現在完全修改我的代碼（使用框架的塊從其他人的迭代，添加了一堆東西。雖然，請看看）

You cannot go over 21. \n If you or the dealer run out of money, the game will end. \n Would you like to start a game now? (y/n)") 
    if choice == 'y':

    elif choice == 'n': 
     menu == 'a' 

elif menu == 'c': 
    decision = 'q' 
    print "Goodbye~" 

兩個主要問題。有時候，當我站立並且結束時，我會收到此錯誤消息。

Traceback (most recent call last): 
    File "C:\Users\Owner\Downloads\Black Jack Revision.py", line 43, in <module> 
    showHand() 
    File "C:\Users\Owner\Downloads\Black Jack Revision.py", line 23, in showHand 
    print "The dealer is showing a %d" % dealer[0] 
IndexError: list index out of range 

此外，我還沒有找到一種方法讓指令循環回主菜單。我沒有讓菜單變成一個函數，因爲它變得太混亂了，局部變量不再工作。

援助將不勝感激。謝謝。

Answer 1

您是否忘記在decision == 's'的else語句中使用setup()？ dealer將返回到showHand()，它將嘗試訪問dealer[0]。

 else: 
      print "*** *** ***" 
      print "The dealer had a higher total! You just lost mon!" 
      print "*** *** ***" 
      dealer = [] 
      player = [] 
      #here 
      pot = 0 
      dealer_money += total 
      total = 0 

當我添加了這個改變後，我打了幾次stand（「S」），並且你的錯誤沒有被複制。然而，碰到它幾次後發生了新的錯誤。

Traceback (most recent call last): 
File "SO.py", line 168, in <module> 
    setup() 
File "SO.py", line 27, in setup 
    deck.pop(dealDealer) 
IndexError: pop index out of range 

該套牌在任何情況下都不會重新初始化。
