检查变量的多个值 [英] Checking multiple values for a variable

问题描述

original = raw_input('Enter a word:')

if len(original) > 0 and original.isalpha():
    word = original.lower()
    first = str(word)[0]
    print first
    if str(first) == "a" or "e" or "i" or "u" or "o":
        print "vowel"
else:
    print "consonant"

我想检查一个单词是否以元音或辅音开头.但是，这部分不起作用:if str(first) == "a" or "e" or "i" or "u" or "o"

I want to check if a word starts with a vowel or consonant. However, this part does not work: if str(first) == "a" or "e" or "i" or "u" or "o"

那么你将如何检查第一个字母是a"或e"还是i"或u"或o"?

So how would you check if the first letter is either "a" or "e" or "i" or "u" or "o"?

推荐答案

你最好使用 in

    if len(original) and original.isalpha():
        word = original.lower()
        first = word[0]
        print first
        if first in ('a','e','i','o','u'):
            print "vowel"
        else:
            print "consonant"

你也做错了，如果你想使用 OR 子句，你必须像这样使用，但这不是更好的 Pythonic 方式:

also you are doing it wrong, if you are trying to use OR clause you must use like this BUT it's not the better pythonic way:

 if first =='a' or first =='e' or first =='i' or first =='o' or first =='u':
