I dont understand what am I doing wrong with the challenge?

So this is my code. I don't know whats wrong but this should work? Can someone please help?

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

The code fails for the following reasons:

  • the string passed into word does not have a remove attributes. Instead, create a list out of word first. Remember to convert back to a string using the join() method before returning word
  • By using series of or conditions, the removals will stop on the first vowel not found. Instead, you will need to use a loop check each character in word character list.
  • Without a loop, repeated vowels would not be removed, only the first occurrence.

Post back if you need more help. Good luck!!

Ok so, in the end, do I have to convert my list back to a string before returning it? For your second point you mean to say I need to use a for loop? I am sorry I don't quite understand what or-ed expressions are?

Yes, you'll need to convert to a list at the start and back to a string at the end. Yes, you will need a loop. By or-ed expressions, I meant a series of or conditions.

I've corrected my answer to reflect this.
