Answer 1

1. If you doing pygame.init() then solve the problem video system initialized. but you get the next error like:

(AttributeError: tuple object has no attribute 'fill') this.

2. this problem is solving when you doing this

screen = pygame.display.set_mode((600, 400))

but not doing like

screen = screen_width, screen_height = 600, 400

3. Then the full problem is solved.
