345. Reverse Vowels of a String*

Write a function that takes a string as input and reverse only the vowels of a string.

Example 1:
Given s = "hello", return "holle".

Example 2:
Given s = "leetcode", return "leotcede".

Note:

The vowels does not include the letter "y".

My code

class Solution(object):
    def reverseVowels(self, s):
        """
        :type s: str
        :rtype: str
        """
      vowelList=['A','a','O','o','E','e','I','i','U','u']
        lowIndex = 0
        highIndex = len(s)-1
        s= list(s)
        while lowIndex<=highIndex:
           if s[lowIndex] in vowelList and s[highIndex] in vowelList:
               s[lowIndex],s[highIndex]=s[highIndex],s[lowIndex]
               lowIndex +=1
               highIndex -=1
           elif s[lowIndex] not in vowelList and s[highIndex] in vowelList:
               lowIndex +=1
           elif s[lowIndex]  in vowelList and s[highIndex] not in vowelList:
               highIndex -=1
           else:
               lowIndex +=1         
               highIndex -=1    
        return ('').join(s)

Notes:

s[lowIndex],s[highIndex]=s[highIndex],s[lowIndex]

('').join(s
