Structuring our programs

So far...


Now...

"""
Today's problem:
    
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.
"""
# see zoo.py


"""
Getting started with data
----

To read data from an external file, we need to make sure that 
we understand the file system on our computers.

Importantly:
    - where does the python program that we're editing exist
    - where does the data file that we want to work with exist

When working with files, we do three things:
    1. open the file
    2. do stuff with the contents of the file
    3. close the file
"""

# opening a file example with animals.txt


"""
Reading from a file and the "cursor"
----

When python opens a file (successfully), 


file.readline() function
---

1. Does this function give me any information back?
2. what is this function's name?
3. what information does this function need to run?

"""

# reading multiple lines from a file

"""
Today's problem, updated:
    
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. Read and display the information
about what animals exist in the zoo from the animals.txt file.
