"""This is an example of a program that reads and alanyses a data
file - a "half way" example during a Python course when we've
covered a lot of the fundamentals, but not gone on to write out
own objects or use dictionaries or regular expressions ... for
newcomers to programming, such confidence building practicals
are so useful as we go! """
