如何让它识别字符串中的不同类型?您需要存储输入,然后将其与所需内容进行比较,例如:
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")
在我看来,更好的方法是这样做:
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
因为它更容易管理和读取不同的输入。您只是在测试e的值是否为真(字符串不为空,因此为真) 您也没有存储输入
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]()
高度可扩展的代码
selection = input("Would you like the author's nationality to be: English or French? ")
if selection == e:
print("Tartuffe")
elif selection == d:
print("Taming of the Shrew")
说得好。“你难道不喜欢一流的东西吗?”Makoto挑衅地说!这和函数指针(来自C++)使输入处理变得更加容易。@gnibbler谢谢,捕捉得好!我使用Python2.7进行测试,但忘了更改:)
choices = {'e': ('French', 'Tartuffe'), 'd': ('English', 'Taming of the Shrew')}
cstr = ', '.join('%r = %s' % (k, choices[k][0]) for k in sorted(choices))
prompt = 'What would you like the author\'s nationality to be (%s): ' % cstr
i = input(prompt).lower()
print('%s: %s' % choices.get(i, ('Unknown', 'Untitled')))
