sum += item

You very rarely have to count your way through a list (or any other iterable) in Python. You can just loop through the members of the list directly.

Treehouse Guest TeacherWhile this will work, why are you counting your way through the list?
for x in list:Also, you probably don't want a variable named
listsince that'll override thelist()type/function and prevent you from being able to make lists that way (it won't matter in the code challenges, but you'll definitely want to avoid it in your own code).
