==================================
Be-A-Computer: Functions and Lists
==================================

The purpose of these problems is to allow you to test your
understanding of functions and lists. They should not take
more than an hour to complete.

You should do these warm-up exercises by hand. We provide
files that will allow you to check your answers.

To get started, run ``git pull upstream master`` to make
sure you have the latest files. You can check your answers by 
running the Python program ``functions-lists.py`` in ``pp/bac/``
