pygame error: Tuple has no attribute get_size()

Question

I have tried everything I can think of to get this background to work, this is the closest I have gotten as it breaks no other bits of my code. I am unsure why get_size() doesn't work.

gameDisplay = pygame.display.set_mode = ((display_width, display_height))
myFont = pygame.font.SysFont("monospace", 15)
pygame.display.set_caption("Catastrophee")
background = pygame.Surface(gameDisplay.get_size())
background = background.convert()

This is only a snippet of the code. I have all variables properly defined.

Please help, thanks, Cam.

Answer 1

Maybe this helps?

gameDisplay = pygame.display.set_mode((display_width, display_height)) #removed =
myFont = pygame.font.SysFont("monospace", 15)
pygame.display.set_caption("Catastrophee")
background = pygame.Surface(gameDisplay.get_size())
background = background.convert()

Answer 2

gameDisplay = pygame.display.set_mode((display_width, display_height))

Just delete second = from that line

Answer 3

You should :

gameDisplay=pygame.display.set_mode([screen_width,screen_height])

Not

gameDisplay = pygame.display.set_mode = ((display_width, display_height))
