This sounds like a homework assignment. We don't offer solutions to 
homework, but are glad to help out after you have tried to write a 
program and run into blocks or specific problems.

Are you studying Python? What have you learned that you could apply to 
this problem?

Is the text document available as a computer file or is it on paper?

The specification is what I'd call informal rather than precise. I'd ask 
the author of the specification to make it more precise. I deem this 
important because endless problems arise when the user does not get what 
he wanted from the programmer, architect, engineer, relationship, 
you-name-it, and the reason is the supplier provided what he thought the 
user wanted.

Precise specification helps ensure desired results. Even in human 
relationships!

OK - what next? How do you react to what I said?
