Answer 3

Or perhaps they are new to doing the MIT 6.183, since they posted in that area...

If that is the case, I would start with getting Python 2.x of some sort, even 2.7.x will work fine. 3.x has some command differences that make a few of the lessons more tricky. Then try to work through things and post questions here if you have trouble.
