On Unix/Linux you could use curses:

import curses

def wait4q(stdscr):
    stdscr.addstr("Press 'q' to exit\n")
    while True:
        if stdscr.getch()==ord('q'): break

if __name__=='__main__':
    curses.wrapper(wait4q)

However, curses could be overkill and it is not portable to Windows, AFAIK.
The curses how-to suggest the console module,

which runs on Windows only.
