Only after months of trying to learn Django you run into a wall because you didn't know Python? I think your style of learning is very different from mine :-)
You missed the part where he took 6 hours to install MySql on Windows. It's literally Next -> Next -> Next -> Finish. I guess he probably meant, "Installed and working", ie, connected to it in a meaningful way, etc.
I think the author meant learning where Django ends and Python begins. MVC is one abstract concept built on another, OOP. I can see if someone comes from a non-programming background, it's daunting, outside in.
I could see that. For the past couple of months, I've been lazily trying to learn Ruby-on-Rails without knowing Ruby. I read a bunch of the doc about the framework itself (e.g. routes, RESTful aspects of RoR…), but I know I'll need to get back to some basics on Ruby at some point.
