python books

Is this book for python 3 or 2? There are a few footnotes that talk about differences between the two, but I can't figure out which one of them the actual code examples in the book are "compatible" with.

yeah, i don't know shit about programming.

the thing is, I haven't written one line of code before. I doubt I would learn much from just memorizing stuff from a technical reference catalouge. That would be like learning physics out of a data book, i imagine
