What am i doing wrong

This isn't working. I am trying to use a for loop to go through every letter.

disemvowel.py 
def disemvowel(word):
    vowels = 'aeiou'
    position = 0
    word = word.lower
    for letter in word:
        if word[position] in vowels:
            del word[position]
        position += 1 
    return word

Good idea, but strings can't have items deleted from them. :)

def disemvowel(word):
    vowels = 'aeiou' # You could also include an uppercase of each letter in this string
    position = 0
    word = word.lower # Remember, you will have to return "word" with letters still uppercased. Here you lowercased them all.
    for letter in word:
        if word[position] in vowels:
            del word[position] # TypeError: 'str' object doesn't support item deletion
        position += 1 
    return word

Because you can't delete letters from a string, I would suggest first making a list that included all the letters, remove the letters from it, then "join" the letters back to a string.

If you need more help just let me know.
