How to use sprite groups in pygame

Question

So I\'ve gotten to the point in my program where I need to create a group for some sprites that the player can collide with without dying (like some other sprites I may have

I know this question has already been answered, but the best method is like what kelwinfc suggested. I'll elaborate so it's more understandable.

# First, create you group
gems = pygame.sprite.Group()

class Jewel (pygame.sprite.Sprite): # Inherit from the Sprite
    def __init__ (self, *args): # Call the constructor with whatever arguments...
        # This next part is key. You call the super constructor, and pass in the 
        # group you've created and it is automatically added to the group every 
        # time you create an instance of this class
        pygame.sprite.Sprite.__init__(self, gems) 

        # rest of class stuff after this.

>>> ruby = Jewel()  
>>> diamond = Jewel()  
>>> coal = Jewel()

# All three are now in the group gems. 
>>> gems.sprites()
[, , ]

You can also add more with gems.add(some_sprite) and likewise remove them with gems.remove(some_sprite).
