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 + random.randint(deltaxmin, deltaxmax),
g.pos + random.randint(deltaymin, deltaymax) )
The above is untested by the way.
