Answer 1

If getkey on arrow keys is giving you letters {A|B|C|D} and getch is giving your their numeric equivalents, call .keypad(True) on the window from which you're reading. doc

stdscr.keypad(True)
key = stdscr.getch()
stdscr.addstr(0, 0, '%s' % key == curses.KEY_UP)

This will have curses interpret the arrow keys' entire escape sequence for you.
