Python Python Collections (2016, retired 2019) Lists Disemvowel

Disemvowel Doubles

My code for this exercise is nearly correct, but it is only able to remove one vowel of a single type at a time.

For example, the exercise passes in 'TuuXSL', and the output should be 'Txsl', but instead my code returns 'Tuxsl'

disemvowel.py 
def disemvowel(word):
    vowels = ['a', 'e', 'i', 'o', 'u', 'A', 'E', 'I', 'O', 'U']
    word_list = list(word)
    for letter in word_list:
        if letter in vowels:
            word_list.remove(letter)
    word = ''.join(word_list)
    return word

If you modify an iterator inside the loop it is controlling, you can cause items to be skipped over. Try using a copy of the item as the iterator.

Also, letters not removed should not be modified. So in your example, if the exercise passes in 'TuuXSL', the output should be 'TXSL' (not 'Txsl').
