Hi Christopher,

This is not a stupid question at all.  It's a very crucial one!

I wrote a small tutorial that shows how to write a program in IDLE:


The screen-captures are a little dated --- I need to fix my Windows box
someday... --- but should help show how to save and run Python programs.

The main idea is that we'll need to save our individual program
instructions in a separate 'program file'.  Think of a Word document,
except that instead of saving English text, we're saving Python source

Once we save our program file to disk, then whenever we want to run that
program, we can tell Python to run across the whole program file.

Hope this helps!
