it asking 3 arguments , have given one. how give 2 more , explain how well? thanks

glancing @ code, line:
pirate = pirate() your pirate class expects self, screen, dx. implicitly provide self.
i can guess @ want, since don't know off bat dx supposed mean in respect game, @ least avoid error:
pirate = pirate(pygame.display.get_surface(), 60)
