Question

Took quite a break from self learning coding, absolutely clueless with this one. Can anyone please explain?
```disemvowel.py
def disemvowel(word):
    vowels = ("a", "e", "i", "o", "u")
    word = input("what word would you like to disemvowel?
> ")
    if not vowels == 'word':
        exit()
    else:
        print ("Removing vowels.")
        word.remove(vowels)
```

Since this is a coding Challenge.  It has  an automated grader, so you are NOT supposed to user interactive input() function.
But you look like you do understand some Python concepts, so let's build on that.
There are many correct approaches to this problem.  One way is to make a new_word that does not contain vowels.  This is accomplished by iterating over the word letter by letter and checking if the letter is NOT a vowel.  
Hint: the grader will check both upper and lower case vowels too!
python
def disemvowel(word):
    vowels = 'aeiouAEIOU'
    # the new_word starts as an empty string
    new_word = ''
    for letter in word:
        # check if the current letter is NOT a vowel, copy it into the new_word
        # and the vowels are skipped
        if not(letter in vowels):
            new_word += letter
    # finally, return the new_word
    return new_word
