Python CSV help :(

So I've recently begun some computer programming classes, and after 10 weeks of classes our first assignment is to take a stock information .csv with a few years of info that looks like this:

date, open, high, low, close, volume, adjusted close NEW LINE 2004-09-17, 110.56, 114.23, 110.2, 112, 5361900, 111.49 NEW LINE 2004-09-16, etc, etc (sorry, can't get reddit to print it properly >.<) Now, we have to make monthly averages, and then figure out the best 6 month period.

I have so far gone over all the notes for lectures, googled around, printed out many sheets and I'm not getting past importing the csv, being able to print it out and making/printing lists of the individual rows of "date", "open", etc.

I'm not expecting anyone to go to the effort of solving this for me, but let me put it this way. The math isn't the problem and I'm comfortable with only the most BASIC level of python and feel this is WAY, WAAYY above my level as do a lot of people in the class. The problem is the class is split between advanced programmers just getting their qualification and newbies who have never programmed before. Can anyone point to a resource/video/text that goes through what I would need to accomplish this because of the four weeks given, I have spent two weeks making a mess and I'm starting to get a bit worried :/
