Usually people use the curses wrapper (which calls initscr along with
other stuff), but here's a simple example that explicitly uses initscr:

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

stdscr.addstr("Hello World!\n")
stdscr.getch()

curses.nocbreak(); stdscr.keypad(0); curses.echo()
curses.endwin()
