One thing to note: I wrote: year = [0] * 1000
Here's another way to get something equivalent: year = [] for i in range(1000): year.append(0) Here, we do an explicit loop to append those thousand zeros into the list. We'll end up with the same situation as before: year is a list of zeros. Why would we want to look at doing it this different approach? See: http://docs.python.org/2/faq/programming.html#how-do-i-create-a-multidimensional-list for details.
