What's the best way to start learning django?
Build something.  Anything.  Keep it relatively simple and short, but start building it and make sure you finish building it.  The project you have in mind right there might be perfect.
Reading documentation and books is extremely helpful, of course, but like any programming the only way to really learn Django is to practice with it.  Building something tangible is pretty much the only way to get that practice.
I really want to build a web application; something simple, maybe a database of Pokémon cards for instance?
I've heard excellent things about Django. Where would be the best place to start?
