在用python制作21点时，如何避免大量的手工操作？

Question

我现在正在做一个小项目。我正在尝试用python制作21点。我能算出牌的总数，但这是一个非常漫长的过程。我必须手动输入每件事。有什么方法可以让我的代码更短吗？如有任何建议，我们将不胜感激。在

您可以使用字典将各种卡片映射到值，然后再使用它，另外在您的blackjack1方法中，您可以print "BlackJack!"仅一次。。。在

例如（demo）：

import random
stringlist=['2','3','4','5','6','7','8','9','10',"J","Q","K","A"]

bmap = { 'A' : 11,
         'K' : 10,
         'Q' : 10,
         "J" : 10,
         '10': 10,
         '9' : 9,
         '8' : 8,
         '7' : 7,
         '6' : 6,
         '5' : 5,
         '4' : 4, 
         '3' : 3, 
         '2' :2
       }
cards=[]
cards.append(stringlist[random.randrange(0,13)])
cards.append(stringlist[random.randrange(0,13)])
print "Got %s and %s. Sum: %s"  % (cards[0],cards[1], bmap[cards[0]] + bmap[cards[1]])
if(bmap[cards[0]] + bmap[cards[1]] == 21):
    print "Yay"
else:
    print "..."
