我目前正在开展一个小项目。我试图在python中制作二十一点。我可以计算卡的总和，但这是一个非常漫长的过程。我必须手动输入每一件事。有什么方法可以缩短我的代码吗？任何建议将不胜感激。

您可以使用字典将各种卡片映射到值，然后使用它，再加上blackjack1方法，您只需print "BlackJack!"一次......
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 "..."

你应该将牌映射到值，然后计算牌的总和，如果是21，然后打印出二十一点！＆＃39;：
import random
cards_values = {'J': 10, 'K': 10, 'Q': 10} # Face cards are 10
suits = ['C','H','D','S'] # Club, Heart, Diamond, Spade
cards = [2,3,4,5,6,7,8,9,10,"J","Q","K","A"]
deck = ['{}{}'.format(i,k) for i in suits for k in cards]
random.shuffle(deck) # shuffle the deck
card1, card2 = deck[:2] # Get two random cards
# Each card is SuitNumber, so a two of clubs is C2
# We need to get the second value to figure out if
# we have a winning blackjack hand
# Here we are checking the second part, if its one of the face cards
# get its value, otherwise the value is its actual number
# We convert it to an integer, so we can sum it and get
# the value of the hand
value_card1 = cards_values.get(card1[1], card1[1])
value_card2 = cards_values.get(card2[1], card2[1])
hand_value = int(value_card1) + int(value_card2)
if hand_value == 21:
print 'BlackJack!'
else:
# We need to check if the difference is
# 1 or 11, and the person had an Ace, he can
# still win
if hand_value - 21 in (1,11) and card1[1] == 'A' or card2[1] == 'A':
print 'BlackJack!'
else:
print 'Oops, you lose. Your cards were {} {}'.format(card1, card2)

这里有一个提示。 绝不是完整或考虑的生产代码。它甚至可能无法运行或编译。我使用额外的数组来映射＆＃34; stringlist＆＃34;中的值。他们的等价值。更正式的实现将使用更高级的数据结构（哈希表，对象）。 ＆＃34; ace＆＃34;需要额外的工作。卡的双重价值（11或1）。
此外，您的＆＃34; stringlist＆＃34;数组实际上是字符串和整数的混合。考虑将此数组中的每个项目都设为字符串。
stringlist=[2,3,4,5,6,7,8,9,10,"J","Q","K","A"]
valuelist= [2,3,4,5,6,7,8,9,10,10, 10, 10, 11]
def getCardValue(c):
for i in stringlist:
if (stringlist[i] == c):
return valuelist[i];
return 0
def isBlackJack(c1, c2):
return (21 == (getCardValue(c1)+getCardValue(c2))
def blackjack1(cards):
if (isBlackJack(cards[0], cards[1])):
print "BlackJack!"
