Sort returns none because it changes your list in-place. Print your list out after calling sort and you should see the new one.

I have created a list by doing sortedKeys = self.addbook.keys() {the self.addbook refers to a dictionary in a custom class}, and then i try to do a sortedKeys.sort() but never get an alphabetical list of the keys. All i get is 'None'. I know that a 'list.sort()' returns a None value but all of the tutorials I see show this giving an alphabetized list.
