========================
Be-A-Computer: Weeks 1-3
========================

The purpose of these problems is to allow you to test you
understanding of the material we have covered so far. They
are divided into three sections; each section 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``, which will pick up a
directory named ``bac1-3``.  


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

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

Warm-up exercise #1: What is the value of ``w`` after evaluating the
following code?

.. literalinclude:: basics.py
   :lines: 2-5

Warm-up exercise #2:  What is the value of ``c`` after evaluating the following code?

.. literalinclude:: basics.py
   :lines: 9-12

Warm-up exercise #3: What is the output generated by the following program?

.. literalinclude:: basics.py
   :lines: 16-22

Functions and Lists
-------------------

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

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

.. literalinclude:: functions-lists.py
   :lines: 1-24

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

.. literalinclude:: functions-lists.py
   :lines: 28-38

Warm-up exercise #3: What is the output of the following code?

.. literalinclude:: functions-lists.py
   :lines: 42-52

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

.. literalinclude:: functions-lists.py
   :lines: 56-67

Dictionaries
------------

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


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

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

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

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

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

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

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

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