[Tutor] small program in Python and in C++

[Rob]

Philosophically, I'm inclined to agree. Defining them all in a clump "up 
top" is the way we did it in Pascal back in '92, as I recall (although I 
could be wrong, it having been a decade back).

I've mainly gotten into doing it this way because my C++ professor and 
the books we use have a decided preference for doing it this way.
