disemvowel function

HI! Can someone explain to me why this is wrong?

def disemvowel(word): word = word.lower() word = list(word) for letter in word: if 'a' in word: word.remove('a') if 'e' in word: word.remove('e') if 'i' in word: word.remove('i') if 'o' in word: word.remove('o') if 'u' in word: word.remove('u') word = "".join(word) return word

disemvowel.py 
def disemvowel(word):
    word = word.lower()
    word = list(word)
    for letter in word:
        if 'a' in word:
            word.remove('a')
        if 'e' in word:
            word.remove('e')
        if 'i' in word:
            word.remove('i')
        if 'o' in word:
            word.remove('o')
        if 'u' in word:
            word.remove('u')
    word = "".join(word) 
    return word

Any letter that is not removed (not a vowel) should not be altered. But this function coverts the entire word to lower case.

Try: "disemvowel("UPPERCASE")" — the result should be "PPRCS".

Thanks! Steven! I actually just used a bunch of ifs to look for lower case vowels and upper case vowels. It’s super inefficient but it did the trick

If you wanted to make the code more compact, instead of testing individually for each possible vowel, you could test each letter for membership in a string of vowels. :wink:
