My version, anyone want to critique it?

It works, but my code always seems to be longer/more complicated than it needs to be...

# Treehouse Challenge number 2
#   - Write a script that takes for a word (or list of words)
#     removes all of the vowels, and gives the word (or words)
#     back.

word = "Treehouse"
print(word)


def remove_vowels(aWord):
    vowels = list('aeiou')
    alist = list(aWord)
    for vowel in vowels:
        while True:
            try:
                alist.index(vowel)
            except:
                break
            index = alist.index(vowel)
            del alist[index]
    print(alist) 

remove_vowels(word)

Comprehensions are a lot of fun, and can definitely be used to shorten this code. Maybe something like...

def remove_vowels(my_word):
    vowels = list('aeiou')
    voweless_word = [letter for letter in my_word if letter not in vowels]
    return voweless_word

I like how conversational the comprehensions can be! :D

Edit: There's a workshop on TeamTreehouse all about comprehensions, and python's docs also has great info.

Wow, I haven't heard of comprehensions before now, it really does trim it down significantly! It's weird how intuitive Python code is, I didn't even have to look at the Python.org doc to get a good idea of what the code does, even though I've never seen this done before. Thanks for the response!
