Lesson 4 in my online Python course is up: Modules and command-line arguments.
This lesson is a little longer than previous lessons, but that's partly because of a couple of digressions at the beginning. Hope I didn't overdo it! The homework includes an optional debugging problem for folks who want to dive a little deeper into this stuff.
