 Exercise: Make a new text file called `animals.py`. Copy the file reading

 2. Go over the exercise and talk about documentation as you do.
 3. How do we know the function works correctly? Try importing and running it
    on a small file.
 4. But what if we want to make changes and make sure it still works afterward,
    or we want to make sure it isn't broken when we add new stuff later?
