Как сделать так, чтобы число из переменной, выводилось на экран в определенную координату?

Помогите пожалуйста, очень надо. Код:

pygame.display.set_caption("TAP NINJA")
running = True

fon = pygame.image.load("tap ninja image/fon1.png")
fon = pygame.transform.scale(fon, (1080, 720))
bg_x = 0
walk_right = [pygame.image.load("tap ninja image/ninja_walk1.png"),
pygame.image.load("tap ninja image/ninja_walk2.png"),

    screen.blit(score, (700, 500))
    print(damage)

    keys = pygame.key.get_pressed()

        damage += tap
    elif keys[pygame.K_e]:
        tap += 1
        damage -= price
        price *= 2

    if player_anim_count == 3:
        player_anim_count = 0
    else:

    pygame.display.update()
