Need help getting line to "draw" in python (pygame)

ive been following a tutorial to learn pygame. the code below is to make a window (640 by 400) that s green. The program is also exposed to draw a red line across the screen. so far i have not been sucessfull in having the line appear. any suggestions?

#! /usr/bin/env python

import pygame

screen = pygame.display.set_mode((640, 400))
running = 1
green = 0, 255, 0
red = 255, 0, 0
point1 = 639, 479
point2 = 0, 0


while running:
    event = pygame.event.poll()
    if event.type == pygame.QUIT:
        running = 0

    screen.fill(green)
    pygame.display.flip()
    pygame.draw.line(screen, red, point1, point2)

in order for some functions to work you have to change your code at the beginning to:

import pygame
from pygame.locals import *
pygame.init()

this makes sure you have all of the essentials and that you "initialize" pygame. without pygame.init() it wouldn't "turn on" most of the functions

You need to call draw.line before the display.flip(), as it is now you are copying the data from the buffer to the display before the lines is drawn.
