Be-A-Computer: Dictionaries
===========================

The purpose of these problems is to allow you to test your
understanding of dictionaries. 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 ``dictionaries.py`` in ``pp/bac/``

Both warm-up exercises and the challenge exercise use the following constants and data:

.. literalinclude:: bac/dictionaries.py
   :lines: 1-13

Warm-up exercise #1: What is the output of the following code?

.. literalinclude:: bac/dictionaries.py
   :lines: 16-26

Warm-up exercise #2: What is the output of the following code?

.. literalinclude:: bac/dictionaries.py
   :lines: 29-43

Challenge exercise: What is the output of the following code?

.. literalinclude:: bac/dictionaries.py
   :lines: 46-62
