python - 如何在 Python 3.2 中选择输入

Question

input("Would you like to read: comedy, political, philisophical, or tragedy?")

a = "comedy"
b = "political"
c = "philisophical"
d = "tragedy"

if a:
    input("Would you like the author's nationality to be: English or French?")
    e = "French"
    d = "English"
    if e:
        print("Tartuffe")
    elif d:
        print("Taming of the Shrew")

当我运行程序时，它只是默认为喜剧，然后是答尔丢夫。
如何让它识别字符串中的不同流派？

Answer 1

你需要存储输入，然后将它与你想要的进行比较，例如:

a = "comedy"
b = "political"
c = "philisophical"
d = "tragedy"

user_input = input("Would you like to read: comedy, political, philisophical, or tragedy?")

if user_input == a:
    user_input = input("Would you like the author's nationality to be: English or French?")

    if user_input == e:
        #do more stuff

一个更好的方法(在我看来)是做这样的事情:

def comedy():
    print("comedy")

def political():
    print("political")

def philisophical():
    print("philisophical")

def tragedy():
    print("tragedy")

types = {"comedy":comedy,
         "political":political,
         "philisophical":philisophical,
         "tragedy":tragedy
        }

user_input = input()

types[user_input]()

因为它更容易管理和读取不同的输入。
