Be-A-Computer: Programming Basics
=================================

The purpose of these problems is to allow you to test your
understanding of basic programming concepts. 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 ``basics.py`` in ``pp/bac/``


Basic Concepts
--------------

You can check your answers by running the Python program ``basics.py`` in ``bac1-3``
