Question

我正在为编程类（Python）的入门做作业，而对于我的作业，我必须掌握52张纸牌的简写形式，并使程序吐出长的形式。（即：红心皇后）

除了我被卡住了，不确定自己在做什么错。这是我的代码：

#taking the shorthand notation of a 52 card playing deck
#and converting it to the long notation
cardValues = {"A": "Ace",
              "J": "Jack",
              "Q": "Queen",
              "K": "King",
              "2": "Two",
              "3": "Three",
              "4": "Four",
              "5": "Five",
              "6": "Six",
              "7": "Seven",
              "8": "Eight",
              "9": "Nine",
              "10": "Ten"}

cardSuit = {"D": "Diamonds",
            "H": "Hearts",
            "S": "Spades",
            "C": "Clubs"}

#grabbing short hand notation
print("Enter card notation: ")
cardNotation = input()


def conversion(cardValues,cardSuit):
    if len(cardNotation) == 2:
        value = cardNotation[0]
        color = cardNotation[-1]
        print (cardValues.get(value) + " of " + cardSuit.get(color))

    #for 10
    elif len(cardNotation) == 3:
        value = cardNotation[:1]
        color = cardNotation[-1]
        print (cardValues.get(value) + " of " + cardSuit.get(color))

    #failsafe
    else:
        print ("INVALID VALUE")

写cardNotation[0:]会给您整个字符串，而不只是一个字母，这就是我想您想要的。您应该索引第一个字母，所以它应该是cardNotation[0]。那是因为当您在索引中使用冒号时，它说“从索引开始，我将括号放在字符串的末尾”。将相同的推理应用于[1:]，并获得正确的颜色索引。

Python-52张牌组简写符号。我哪里做错了？
