Why is my code not working? I have tried it on my own and it seems to be working fine.

Cant figure out why its not working.

disemvowel.py 
vowels = ['a', 'e', 'i', 'o', 'u']
def disemvowel(word):
    word = word.lower()
    word = list(word)
    for letter in vowels:
        if letter in word:
            word.remove(letter)
    return(word)

You have the right idea. Your code will pass with theses corrections:

:point_right: add uppercase vowels to the vowels list

:point_right: remove statement using lower()

:point_right: flip the for and if object targets. For each letter in the word check if the letter is in the vowels list

:point_right: join() the word list into a string before returning it.

:no_entry: Wait! Try to fix your code using the hints above before looking at the corrected code

:white_check_mark: Here's the corrected code:

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

Pretty sure if you make your vowels list include both under and uppercase letters, it'll help. The challenge says to make sure to check for upper and lowercase letters :) Saying that, you're not going to need the word = word.lower() line as well. Hope I helped!

I know what the problem is, the loop stops once it finds vowel and then misses the same vowel if it comes up again in the word. Any idea how I can do that? I am thinking I need to use "pass" in some way but I tried and it didn't work.
