Something like: import random class Gazelle(object): def __init__(self): self.pos = 0, 0 # create a list of instances gazelles= [ Gazelle() for x in range(5)] # update gazelle positions deltaxmin, deltaxmax = -100, +100 deltaymin, deltaymax = -100, +100 for g in gazelles: g.pos = (g.pos[0] + random.randint(deltaxmin, deltaxmax), g.pos[1] + random.randint(deltaymin, deltaymax) ) The above is untested by the way. - Paddy. -- http://mail.python.org/mailman/listinfo/python-list
