Well, it is certainly possible. First, the hard way: you use the ANSI termainal control commands (you can find the reference on the web, or if you need it I can send you an HTML file containing them). Second, the better way: you can use the ncurse library (via the curses Python module). There you'll get a whole toolkit for TUI (Terminal User Interface ;) ).
BTW, if you happen to need this while drawing only a single line, the "\r" char gets you at the beginning of the current line ! So flushing stdout and then sending the "\r" char will allow you to overwrite the current line.
