How to solve pc gaming error is water game?

Question

I'm trying to make a game in Python using PyGame, but I receive this traceback:

  Traceback (most recent call last):
  File "C:\Users\usuario\Documents\abscorp\232\232.py", line 150, in 
<module>
    hits = pygame.sprite.groupcollide(drop, player, True, True)
  File "C:\Python27\lib\site-packages\pygame\sprite.py", line 1536, in 
groupcollide
     c = SC(s, groupb, dokillb, collided)
  File "C:\Python27\lib\site-packages\pygame\sprite.py", line 1500, in 
spritecollide
    for s in group.sprites():
AttributeError: 'Player' object has no attribute 'sprites'

There are certain drops of water that should fall from pipes randomly but IDLE keeps giving me an error message. I believe the part that produces the error is the following: "pygame.sprite.groupcollide".

The full code is attached below.

Error message shows that it has problem with groupcollide so check it in documentation .

groupcollide(group1, group2, dokill1, dokill2, collided = None) -> Sprite_dict

Find all sprites that collide between two groups.

Documentation shows that it needs two groups - it means pygame.sprite.Group
but you use player which is pygame.sprite.Sprite

To check collision between Sprite and Group you have

• pygame.sprite.spritecollide()
• pygame.sprite.spritecollideany()
