Full traceback:

Traceback (most recent call last):
  File "collision.py", line 156, in <module>
    check_collision() 
  File "collision.py", line 84, in check_collision
    b = pygame.sprite.truth(a)
AttributeError: 'module' object has no attribute 'truth'

No function named "truth" is mentioned in the sprite module documentation. I see that this line is trying to operate on the results of the previous line, a call to groupcollide, which, according to the documentation, returns a dictionary of any colliding sprites. If you simply want to know if any sprites collide, you just need to check if the returned dictionary is non-empty (ie: a != {}).
