kbhit/getch python equivalent

[alb]

Hi everyone,

I'm looking for a kbhit/getch equivalent in python in order to be able
to stop my inner loop in a controlled way (communication with external
hardware is involved and breaking it abruptly may cause unwanted errors
on the protocol).

I'm programming on *nix systems, no need to be portable on Windows. I've
seen the msvcrt module, but it looks like is for Windows only.

Any ideas/suggestions?

Curses?

Signals, ncurses, termios.

Catch KeyboardInterrupt and hit Ctrl-C.

A curses example

import curses

stdscr = curses.initscr()
curses.cbreak()
stdscr.keypad(1)

stdscr.addstr(0,10,"Hit 'q' to quit ")
stdscr.refresh()

key = ''
while key != ord('q'):
key = stdscr.getch()
stdscr.addch(20,25,key)
stdscr.refresh()

curses.endwin()
