Need help with question involving list methods, list formatting and exceptions.

Hi, My code for this question produces an error yet when I run it in my python environment, it works. I feel it could be a formatting problem rather than a code problem but I await advice from others. Please help. Thanks

disemvowel.py 
def disemvowel(word):

    final_word = list(word)

    for letter in word:
        try:
            final_word.remove('a')
        except ValueError:
            pass

        try:
            final_word.remove('a'.upper())
        except ValueError:
            pass

        try:
            final_word.remove('e')
        except ValueError:
            pass

        try:
            final_word.remove('e'.upper())
        except ValueError:
            pass

        try:
            final_word.remove('i')
        except ValueError:
            pass

        try:
            final_word.remove('i'.upper())
        except ValueError:
            pass

        try:
            final_word.remove('o')
        except ValueError:
            pass

        try:
            final_word.remove('o'.upper())
        except ValueError:
            pass

        try:
            final_word.remove('u')
        except ValueError:
            pass

        try:
            final_word.remove('u'.upper())
        except ValueError:
            pass

    return final_word

The challenge wants you to return a word with the vowels missing. There is nothing wrong with your code and it does return the correct letters, however, it returns them as a list of consonants. If you change your return statement to join the list into a single string, you will pass the challenge:

def disemvowel(word):

    final_word = list(word)

    for letter in word:
        try:
            final_word.remove('a')
        except ValueError:
            pass

        try:
            final_word.remove('a'.upper())
        except ValueError:
            pass

        try:
            final_word.remove('e')
        except ValueError:
            pass

        try:
            final_word.remove('e'.upper())
        except ValueError:
            pass

        try:
            final_word.remove('i')
        except ValueError:
            pass

        try:
            final_word.remove('i'.upper())
        except ValueError:
            pass

        try:
            final_word.remove('o')
        except ValueError:
            pass

        try:
            final_word.remove('o'.upper())
        except ValueError:
            pass

        try:
            final_word.remove('u')
        except ValueError:
            pass

        try:
            final_word.remove('u'.upper())
        except ValueError:
            pass

    return "".join(final_word)

Haha, It worked. Thanks Charlie, I completely forgot to turn it back to a string.

Hi Anyone, If you ever land here, here is the far more elegant code for the same challenge:

def disemvowel(word):

vowels = ["a", "e", "i", "o", "u"]
final_word = list(word)

for letter in word:

    if letter.lower() in vowels:

        final_word.remove(letter)

return "".join(final_word)
