Depending on the terminal type you can use control codes to
move the cursor. Thus on most Unix terminals you can use Ctrl-U
to delete the line, thus if you wriote a Ctrl-U character before each
line and suppress the newline at the end it will appear that all
output is on a single line.

On a DOS ANSI terminal I can't recall the Ctrl code used, but it
is possible.

Another option is to use the curses module which allows you
to specify the screen coordinates where you write. A similar
module is available for DOS on the web - I think I saw it on
the vaults of Parnassus.
