[Tutor] listdir

> >>> import os

This makes the name 'os' available to Python.

But Python does not know the names of anything inside os.
To use a function within os you must prefix the function name 
with os, thus:

>>> os.listdir(....)

The "Simple Sequences" and "Modules and Functions" topics 
in my tutorial address this issue in more depth.
