Python实现 "反转字符串中的元音字母" 的方法

#coding=utf-

def reverseVowels(s):
    """
    :type s: str
    :rtype: str
    """
    sStr = list(s)
    voList = {'a':, 'A':, 'e':, "E":, 'i':, "I":, 'o':, 'O':, 'u':, 'U':}
    front =
    length = len(sStr)
    back = length -
    while front < back:
        while front < length and sStr[front] not in voList:
            front +=
        while back >=  and sStr[back] not in voList:
            back -=
        if front < back:
            sStr[front], sStr[back] = sStr[back], sStr[front]
            front +=
            back -=
    return "".join(sStr)

str="hello world!"
print(reverseVowels(str))

输出

hollo werld!
