iterating through word

Question

def disemvowel(word):
    vowels = ["a", "e", "i", "o", "u", "A", "E", "I", "O", "U"]
    for letter in vowels:
        try:
            word = word.remove(letter)
            print "yay"
        except:
            print "nay"
disemvowel("Kevin")
I know that you cant iterate through words easily but how else are you supposed to get it? I tried using replace but the challenge in Python Collections yelled at me :'(:
def disemvowel(word):
    vowels = ["a", "e", "i", "o", "u", "A", "E", "I", "O", "U"]
    for letter in word:
        if letter in vowels:
            word = word.replace(letter,"")
    print word
disemvowel("Shut Up")
disemvowel.py
def disemvowel(word):
    vowels = ["a", "e", "i", "o", "u", "A", "E", "I", "O", "U"]
    for letter in vowels:
        try:
            word = word.remove(letter)
            print "yay"
        except:
            return word
            print "nay"

you can loop through strings and compare each element (each letter) however you like. then call the remove method. but watch for a common issue - modifying lists while looping through them. to avoid this, make a copy of the list and modify that while looping through the original (or vice versa). the remove method removes the stated index, then shifts the following elements left, but the loop won't account for that. this leads to skipping elements and incorrect results.
