Ah, thanks. It was far too simple. What I was looking for was
simply:
import readline
then replace sys.stdin.readline() with raw_input()
> You may also consider using the cmd module.
I'll have to keep the cmd module in mind for other applications
(where the user is entering commands). Rather than commands,
the user of this application is entering data that changes
little (if any) from one line to the next, so raw_input() is
exactly what I needed.
