.remove challlenge

What's my problem? Why does my code not work? I think I have it all, the remove, except ValueError, and the upper and lower cases...

disemvowel.py 
def disemvowel(word):
    try:
        word.remove('a', 'e', 'i', 'o', 'u', 'A', 'E', 'I', 'O', 'U')
    except ValueError:
        pass
    return word

There are two mistakes:

  1. Python doesn't have a method called remove on strings. It only has that method on lists.
  2. Even if you first convert the string into a list, the remove method on lists doesn't support to remove multiple arguments at once. You shouldn't make up your own way of using a function, it might not work! You should always check the documentation for new functions.
  3. Lastly, remove only removes the FIRST element that's the vowel.

EDITED

Solution:

def disemvowel(word):
    result = ''
    for letter in word:
        if letter.lower() not in 'aeiou':
            result += letter
    return result

I hope this helps. ~Alex
