disemvowel1 challenge issue

Hi, I am doing the disemvowel challenge from Python Collection. The question asks to create a function that remove all vowels (uppercase and lowercase) in a word and then return it.

So I create 2 list of vowels, one is for uppercase letters and the other is for lowercase letters. Then I run a for loop through the input word and if all the letter in that word also in my vowels lists, I will remove it with word.remove(letter).

But at the end, it says I am not correct, I try to look at my code and I really don't see anything off about my code. I would be very appreciate if you can point out what I did wrong.

Thank you

disemvowel.py 
def disemvowel(word):
    vowels_lower = ['a','e','u','o','i']
    vowels_upper = ['A','E','U','O','I']
    for letter in word:
        if letter in vowels_lower or letter in vowels_upper:
            word.remove(letter)
        else:
            return word

I believe you can't use the remove method on strings, so first, you'll have to turn word into a list. Then use a for loop to iterate through word, and checking if each letter is contained in 'aeiouAEIOU'. Then proceed to use .remove() and .join() to return as a string. In case i don't explain well enough, here's the code: 

def disemvowel(word):
    mylist = list(word)
    for letter in word:
        if letter in 'aeiouAEIOU':
            mylist.remove(letter)
    return ''.join(mylist)

oh, that's right, I totally forget that the input is string type and therefore I need to convert it back to list in order to compare. Thank you for remind me
