Question

我正在做一个控制台个性测试，我想为玩家输入的黄道十二宫打印报价。我不想使用大量的if语句，我可以使用字典和循环吗？

其中键是十二生肖，值是特定的引号，然后使用循环和简短的if语句用给定的输入循环键，并打印相应的值，即引号。

这是我的代码：

sign = input("What is your zodiac sign ? (Enter one of these: aries, taurus, gemini, cancer, leo, virgo, libra, scorpio, sagittarius, capricorn, aquarius, pisces )  ---> ")


zodiac_signs = {
  "aries": "quote", 
  "taurus": "quote", 
  "gemini": "quote", 
  "cancer": "quote", 
  "leo": "quote", 
  "virgo": "quote", 
  "libra": "quote", 
  "scorpio": "quote", 
  "sagittarius": "quote", 
  "capricorn": "quote", 
  "aquarius": "quote", 
  "pisces": "quote"
  }

接下来我该怎么办？

Answer 1

您只需使用以下命令即可从字典中获得十二生肖

sign = input("What is your zodiac sign ? (Enter one of these: aries, taurus, gemini, cancer, leo, virgo, libra, scorpio, sagittarius, capricorn, aquarius, pisces ) ---> ")

zodiac_signs = { "aries": "quote", "taurus": "quote", "gemini": "quote", "cancer": "quote", "leo": "quote", "virgo": "quote", "libra": "quote", "scorpio": "quote", "sagittarius": "quote", "capricorn": "quote", "aquarius": "quote", "pisces": "quote" }

try:
    print(zodiac_signs[sign])
except(Exception e):
    print("That's not a zodiac sign")

Answer 2

Python字典具有一个专门解决此问题的get方法。

print(zodiac_signs.get(sign, "That's not a zodiac sign"))

如果它在dict中，则通过返回给定键的值来运行，否则返回给定的默认参数。

加合Challe所说的话，您可能还希望小写输入，以使键匹配，即使它们的首字母使用大写也是如此。
