So, with the example file you showed previously, sit down and write
some code. It probably will take less than a screen size full of code
-- maybe 20 lines or so. See what you get for output. You will
certainly get errors -- syntax and runtime. When you get stuck, cut
and paste the code and the trace-back that python gives you to your
email, and people will help you move forward.
