I carry around a little notebook with me all the time. When I'm teaching or meeting with someone I use it as my "extended working memory." I don't save the notebooks or revisit them. Once a notebook is filled I simply throw it away.
Well, with on exception: when I left DBC, I flipped through my most recent notebook, tore out any pages that grabbed my attention, and threw the rest away. These are those notes.

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)

The history of philosophy is to a great extent that of a certain clash of human temperaments. Undignified as such a treatment may seem to some of my colleagues, I shall have to take account of this clash and explain a good many of the divergencies of philosophers by it. Of whatever temperament a professional philosopher is, he tries when philosophizing to sink the fact of his temperament. Temperament is no conventionally recognized reason, so he urges impersonal reasons only for his conclusions. Yet his temperament really gives him a stronger bias than any of his more strictly objective premises. It loads the evidence for him one way or the other, making for a more sentimental or a more hard-hearted view of the universe, just as this fact or that principle would. He trusts his temperament. Wanting a universe that suits it, he believes in any representation of the universe that does suit it. He feels men of o
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.

I stumbled across this quote while reading The Metaphysical Club, a fantastic book about the birth and evolution of the Pragmatic tradition in the United States. What struck me most was that it an almost perfect reflection of how I thought about our work at Dev Bootcamp.
One of the most common questions about Dev Bootcamp I got from students, press, and other entrepreneurs is somethi
