I am trying to create a space invader game. in which I have to display different waves 1,2,3 I have written the code
wave1="bgk.png"
if wave1!=wave:
screen.blit(pygame.image.load(wave),(615,480))
wave="bgk.png"
time.sleep(3)
screen.blit(pygame.image.load(wave),(615,480))
Here 'wave' changes after a certain number of scores are reached but
The problem is that the first image doesn't load before the 3-second break. and after 3 seconds it loads for about 0.1(negligible) amount of time you can see if you look very closely I don't know what is causing this issue please help
The full code is here

I am very new to the coding culture I don't know how to use StackOverflow i might have made some silly mistakes and i am very sorry for that
