# Question about data files
# I will not ask you to read in from a file, but
# you do need to be able to process data that I have
# already read in and put in a list.

If data file is:
bear,180,15
cat,52,10
dog,53,10

then you might get it as a list of strings as this:
[ "bear,180,15", "cat,52,10", "dog,53,10"]
