Making decisions

There are some key super powers that we need 
to write programs with lots of abilities.

1) Memory
2) Re-using code

Boolean data type
---

A new data type!

Like string, int, float, except this data type is extra special!

Boolean expressions
---
Much like we can have arithmetic expressions 
(3 + 7 ** 2) evaluates to a numerical answer,
we can have boolean expressions. Expressions that evaluate to 
a boolean answer.

comparison operators:

Updating zoo.py
----
From last lecture:
    
Write a program, zoo.py, that represents a zoo that we're starting. 
First, this program should greet the user (by name, of course), then 
tell them what animals we have in our zoo.

Update:
Now, we'll ask the user whether they are interested in visiting 
the reptile house or the aviary, then tell them the animals in the
appropriate place based on their answers.

(We'll have two data files—aviary.txt and reptile.txt)

"""
Introduction to data viz
---
We'll use the library matplotlib.pyplot to create graphs in this class

Basics:
    1) import the matplotlib library
    2) use plt.plot(x coordinate, y coordinate) to plot a point
    3) when you're all done, call plt.show()

"""
Example problem:
---

Write a program, distance.py, that reads the data from the two files days.txt and 
distances.txt and graphs them accordingly on a scatter plot.
"""

"""
Example problem, updated:
---

Write a program, distance.py, that reads the data from the *three* files:
days.txt, distances.txt, and modes.txt graphs them accordingly on a scatter plot.

Color days that were a run with one color and days that were a bike ride 
a different color.
