How to synchronize sprite image in pygame

Question

I am looking to create characters in a game using pygame and python version 2.7.6. I have a simple python script that allows me to create a window and print the image on the screen. This works successfully, however it is just a static image.

import pygame


class Game(object):
    def main(self, screen):

        #load first sprite to image for blit"
        image = pygame.image.load('sprites/sprite1.png')
        image2 = pygame.image.load('sprites/sprite2.png')
        image3 = pygame.image.load('sprites/sprite3.png')
        while 1:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                return
            if event.type == pygame.KEYDOWN and event.key == pygame.K_ESCAPE:
                return

        screen.fill((200, 200, 200))
        screen.blit(image, (320, 240))
        pygame.display.flip()

if __name__ == '__main__':
    pygame.init()
    screen = pygame.display.set_mode((640, 480))
    Game().main(screen)

I want to create a more dynamic picture by changing the first sprite with the second and so on, at least three of the sprite may be larger ( sprite1.png, sprite2.png, sprite3.png). How can I cycle images after a specified time interval, for example: 1 second 1/2 second ...

@Puciek , ,

import time

for img in [image, image1, image2]:
    screen.fill((200, 200, 200))
    screen.blit(img, (320, 240))
    time.sleep(1)    # sleep 1 second before continuing
