I thought srings were immutable?

I dont get this, i thought strings were immutable. How does it want me to remove anything from it? I tried append each letter from the word into a list, but i couldent figure out how to do that. Halp?

disemvowel.py 
def disemvowel(word):
    word
    return word

You're right, strings are immutable. So in your function, you'll probably want to create a new string that has all the letters of the old one except the vowels, and then return that.

You could use a list but you could also build a string using concatenation.

Can you elaborate, what do you mean "buildi a string using concatination".

Here's an example of a loop building a new word from the letters of an old word (without any changes):

newword = ""
for ltr in oldword:
    newword += ltr
