PyGame : Showing pictures on pygame

First of all, you need two files. This is "load.py"

import os
import sys
import pygame
def img(nume):
    numeintreg = os.path.join("date",nume)
    image = pygame.image.load(numeintreg)
    image = image.convert()
    return image

This is "main.py". The image "bk2.bmp" can be any image.

import os
import sys
import pygame
import load
def main():
    pygame.init()
    ecran = pygame.display.set_mode((640, 480))
    fundal = load.img('bk2.bmp')
    ecran.blit(fundal, (0, 0))
    pygame.display.flip()
main()
