Using arrow keys with python can be tricky so the code below should help: –
import curses
# get the curses screen window
screen = curses.initscr()
# turn off input echoing
curses.noecho()
# respond to keys immediately (don't wait for enter)
curses.cbreak()
# map arrow keys to special values
screen.keypad(True)
try:
while True:
char = screen.getch()
if char == ord('q'):
break
elif char == curses.KEY_RIGHT:
# print doesn't work with curses, use addstr instead
screen.addstr(0, 0, 'right')
elif char == curses.KEY_LEFT:
screen.addstr(0, 0, 'left ')
elif char == curses.KEY_UP:
screen.addstr(0, 0, 'up ')
elif char == curses.KEY_DOWN:
screen.addstr(0, 0, 'down ')
finally:
# shut down cleanly
curses.nocbreak(); screen.keypad(0); curses.echo()
curses.endwin()
