Just code towards your goal. Most of the theory of computer science that you'll need implemented along the way will be done for you via something low-level that you don't really need to worry about because it'll come for free (in python or in django). If you run into things that you find you're curious about them in a deeper level, that's when you should look for more technical material to support that.
