Disemvowel.py Code below always returns a string with now vowels....Not sure what is wrong?

def disemvowel(word): words = word.lower() words = list(words) vowels = ['a','i','e','o','u'] li = [] for i in words: if i in vowels: continue else: li.append(i) new = ','.join(li) return new

disemvowel.py 
def disemvowel(word):
    words = word.lower()
    words = list(words)
    vowels = ['a','i','e','o','u']
    li = []
    for i in words:
        if i in vowels:
            continue
        else:
            li.append(i)
    new = ','.join(li)
    return new

You're returning a string with commas between each letter. Try

"".join(li)
# rather than
",".join(li)

.join will join each item in a list with whatever is in the quotes, empty quotes (no space) will put literally nothing between each item of the list and return as a string.

You may also want to, instead of

word = word.lower()

# you might want to try
if i.lower() in vowels

So if any capital letters are passed in the argument, they will be returned as capital letters.
