python 3.x - Image doesn't load in pygame -

i'm having trouble uploading image in pygame. here's code.

import pygame, sys  pygame.locals import *  def capitals():      pygame.init()     displaysurf = pygame.display.set_mode((500, 400))     pygame.display.set_caption('capitals')     black = (  0, 0, 0)     white = (255, 255, 255)     red = (255, 0, 0)     green = (0, 255, 0)     blue = (0, 0, 255)      displaysurf.fill(white)     displaysurf=pygame.image.load('usa.jpg').convert()     while true:      event in pygame.event.get():       if event.type==quit:        pygame.quit()        sys.exit()       pygame.display.update() 

the picture isn't having problem loading on python page, there no "cannot open file error", on actual pygame window, image isn't loading.

to display image on screen, have draw on display surface (using blit). doing here

displaysurf=pygame.image.load('usa.jpg').convert() 

is loading image , assign displaysurf variable.

so use instead:

image=pygame.image.load('usa.jpg').convert() # load image displaysurf.blit(image, (0, 0)) # blit screen
