Speed issue with sprite update

[Windspar]

Yes. Just looks up what in screen area. All the rest is ignore. But need to remove try and except. That was for something I was testing. Forgot to remove it.
Example just for background or foreground.

    def draw(self, surface, camera):
        location = camera.position / self.tilesize
        x_range = self.get_range(camera.position.x, self.display_size.x, self.mapsize[0])
        y_range = self.get_range(camera.position.y, self.display_size.y, self.mapsize[1])
        for x, y in product(x_range, y_range):
            position = int((x - location.x) * self.tilesize), int((y - location.y) * self.tilesize)
            tile = self.map_data[y][x]
            if tile:
                surface.blit(self.map_images[tile], position)

    def get_range(self, start_position, end_position, max_position):
        start = start_position / self.tilesize
        start_range = max(int(start), 0)
        end_range = min(int(start + end_position), max_position)
        return range(start_range, end_range)
