I have ensured that all letters are small before I check..

So where am I going wrong? I loop through every letter in the word and I remove the original letter that is contaiend in vowels...What am I doing wrong?

disemvowel.py 
def disemvowel(word):

    vowels = ["a", "e", "i", "o", "u"]
    wordList = list(word)
    for letter in wordList:
        letterEdit = letter.lower()
        if letterEdit in vowels:
            wordList.remove(letter)
    result = ("").join(wordList)
    return result

You are iterating AND changing the iterable at the same time! So every time you remove an element from the list, your loop gets shortened...

Simply change to

for letter in list(word):
...

will do.

P.S. this challenge can be done in one line : D

def disemvowel(word): return "".join(list(filter(lambda x: x if x.lower() not in "aeiou" else "", word)))
