There is an image of a school growing up in my mind all the time; a school where some actual and literal constructive activity shall be the centre and source of the whole thing, and from which the work should always be growing out in two directions — one the social bearings of that constructive industry, the other the contact with nature which supplies it with its materials.

— John Dewey to Alice Chipman Dewey and children, November 1st, 1894, John Dewey Papers

Questions

How do I get it to return per line, isn't that the point of this exercise? For instance, how would I get it to return each value, such as line 35's list "total = 0" on one line, next "total = 0 + 11", next line "total = 11+22".

I could not find a way to do it like, 'running_total = return item[0], return item[0] + item[1]...item[i]'.

First, it's good that you understand what you need to do and are referring to the last item of the list as item[i]. Keep in mind that if the list is in the variable list then to get the item at, say, index 10, we want list[10], not item[10]. Imagine if you could write code like this:

def sum(list)
