Use atexit.register() to register a cleanup function which is called 
when the program exits:

import atexit
import curses

def cleanup():
     curses.nocbreak()
     stdscr.keypad(0)
     curses.echo()
     curses.endwin()

atexit.register(cleanup)

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

curses.start_color()
curses.init_pair(1, curses.COLOR_GREEN, curses.COLOR_BLUE)
curses.init_pair(2, curses.COLOR_YELLOW, curses.COLOR_BLACK)

stdscr.bkgd(curses.color_pair(1))
stdscr.refresh()

win = curses.newwin(5, 20, 5, 5)
win.bkgd(curses.color_pair(2))
win.box()
win.addstr(2, 2, "Hallo, Welt!")
win.refresh()

c = stdscr.getch()
