Hmm. I think curses is the module I need, but I can't find documentation and
the module is written in c so I can't read that. If I run your example, I get
Traceback (innermost last):it:~/oefen/python$ python modcurse.py
                             File "modcurse.py", line 6, in ?
                                                                 key = curses.getch()
     AttributeError: getch
                          20:17:46:17/516:gerrit at gerrit:~/oefen/python$
and my terminal is totally wrong (if I press enter I don't get a newline, etc.)

The important part of dir(curses):
...
KEY_SUNDO', 'KEY_SUSPEND', 'KEY_UNDO', 'KEY_UP', '__doc__', '__file__', '__name__', '__version__', 'beep', 'cbreak', 'doupdate', 'echo', 'endwin', 'error', 'flash', 'flushinp', 'initscr', 'intrflush', 'isendwin', 'keyname', 'meta', 'newwin', 'nl', 'nocbreak', 'noecho', 'nonl', 'noraw', 'raw', 'ungetch', 'version']

Ah, there is some little documentation in the source.

I found it, it must be: win.getch()

Thanks!

regards,
Gerrit.
