Earlier quoted context omitted.
agreed... despite of a nice interface, the site does lack organization and some super beginner stuff, I did overlook the absence of those...
Super Beginner stuff is on the standard python tutorial. That normally doesn't need to be on every website.
Another thing to keep in mind: this kind of beginner will also have trouble finding these "standard" tutorials that have up-to-date info. No, it's not that they can't use Google, but they don't have enough technical sense to tell what's a good source of this installation info from what's a bad source. Hence, it's good to have this super-basic info packaged into any kind of tutorial that purports to be for "beginners".
