这个也是很简单，不过要注意元音字母还包括大写字母。。。
class Solution(object): def reverseVowels(self, s): v = ['a','e','i','o','u','A','E','I','O','U'] vovs = [] s = list(s) for i in xrange(len(s)): if s[i] in v: vovs += s[i], s[i] = None #vovs.reverse() #print vovs,s for i in xrange(len(s)): if s[i] == None: s[i] = vovs.pop() #print s return ''.join(s)
