我已经设置了所有 52 张卡片，我尝试使用 for 循环 打印所有 52 张卡片。 我现在不知道如何设置我的 for 循环。
def define_cards(n):
rank_string = ("ace","two","three","four","five","six","seven","eight","nine","ten","jack","queen","king")
suit_string = ("clubs","diamonds","hearts","spades")
cards = []
for suit in range(4):
for rank in range(13):
card_string = rank_string[rank] + " of " + suit_string[suit]
cards.append(card_string)
print "The cards are:"
for i in range(52): #how to make this for loop work??
print i, card_string[i]
我想这样打印
The crads are:
0 ace of clubs
1 two of clubs
2 three of clubs
...
49 jack of spades
50 queen of spades
51 king of spades
请您参考如下方法:
您的函数 define_cards 必须返回列表。在末尾添加 return cards。
然后你必须实际调用/执行这个函数。
然后您可以访问此列表中的各个卡片:
cards = define_cards()
for i, card in enumerate(cards):
print i, card
但是，如果您正在寻找“更像 pythonic”的解决方案，请尝试以下方法:
import itertools as it
rank_string = ("ace","two","three","four","five","six","seven","eight","nine","ten","jack","queen","king")
suit_string = ("clubs","diamonds","hearts","spades")
print 'The cards are:'
for i, card in enumerate(it.product(rank_string, suit_string)):
print i, '{0[1]} of {0[0]}'.format(card)
