roman_result + "M" would also work, right/ I'm just trying to save  
time on typing in the code, right

is that somewhat like digital_result = digital result - int(1000)?

running = True and
while running

is how I've tended to set

(my pseudocode)

I have already gained some familiary with separating data manipulation  
(data and logic, as a whole) from the code for the user interface,  
that's something that oen of my advisors has been big on.
