Kenneth, This is good advice generally. Still, I like to approach projects this way because I believe it forces me to flex all sorts of mental developer muscles that would otherwise atrophy. I don't want to lose the ability to construct and explore a data model in my head and I find it educational to work bottom-to-top. Perhaps I'm just a masochist?
Also: I come from an enterprise, IDE-heavy Java background and from there moved into full stack JavaScript. In both of these languages I have experience with fantastic step-through debuggers and inspectors. In Python I've so far been constrained to logging, the REPL, and to pdb.set_trace(). I only just found that I can use pdb interactively when Django is in Debug mode. Can you recommend a better, more feature-rich way to step through my Python programs?
