Received unexpected letters

Hi, The below code worked outside of the challenge but it doesn't work inside. Can someone spot the problem?

Also, what is a cleaner way to do this? There must be a better way than adding try and except for each vowel.

Thank you. Trish

disemvowel.py 
def disemvowel(word):
    word = word.lower()
    wordstring = [] 
    for i in word: 
        wordstring.append(i)  
    for i in wordstring:
        try:
            wordstring.remove('a')
        except ValueError:
            pass
        try:
            wordstring.remove('e')
        except ValueError:
            pass
        try:
            wordstring.remove('i')
        except ValueError:
            pass
        try:
            wordstring.remove('o')
        except ValueError:
            pass
        try:
            wordstring.remove('u')
        except ValueError:
            pass

    return wordstring

There are two issues with the current code:

  • wordstring needs to be joined back into a single word
  • The capital letters are not preserved in the returned word. Be mindful of how you are using lower()

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

Thank you! I got it to work. I also found a better way to solve the problem using the str.replace() method.
