remove

I don't understand what I am doing wrong.

disemvowel.py 
def disemvowel(word):
    vowels= ("aeiou")
    wordlist = vowels
    for words in word:
        print(words.upper())
        print(words.lower())
    for letter in wordlist:
        words.remove(letter)
    return word

I see a few issues:

  • after the first loop ends, "words" (plural) is out of scope (and not available inside the 2nd loop)
  • "remove" is a list function and not available on strings
  • the "remove" function only removes the first occurrence of the matched item, not all of them
  • you need to remove either case, but the code currently only check lower case
  • "word" is never modified, and is being returned unchanged
