Disemvowel challenge help

I'm uncertain why my code is not passing this challenge. Guidance as to what must be fixed is appreciated.

disemvowel.py 
def disemvowel(word):

    word_characters = list(word)
    vowels = ['A', 'a', 'E', 'e', 'I', 'i', 'O', 'o', 'U', 'u']

    for character in word_characters:
        if character in vowels:
            word_characters.remove(character)
        else:
             continue


    return ''.join(word_characters)

I believe I've figured out the issue. When removing a letter that happens to be a vowel, it shifts characters towards the front of the list while I'm iterating towards the back.

You're right -- your code only removes the first instance of each vowel it finds.

Try this out!

def disemvowel(word):
    word_characters = list(word)
    vowels = ['A', 'a', 'E', 'e', 'I', 'i', 'O', 'o', 'U', 'u']

    word_characters = [letter for letter in word_characters if letter not in vowels]

    return ''.join(word_characters)
