Hi,
yet another option is to use [1]
bodyInteractions = b.intrs()
returning list of body interactions. If you are interested merely in the number, then
len(bodyInteractions)
returns you the result, or you can do some more fancy postprocessing (like counting only interactions with spheres, excluding walls:
def isSphereSphere(i):
    bs = [O.bodies[id] for id in (i.id1,i.id2)]
    return all(isinstance(b.shape,Sphere) for b in bs)
len([i for i in bodyInteractions if isSphereSphere(i)])

The optimal choice really depends on your needs..

cheers
Jan
