You don't want a herd of the Platonic type of gazelle, you want a herd
of individual instances of the class of gazelle. No problem.
Something like
class Gazelle(object):
def __init__ (self, color, position)
self.color = color
self.position = position
# ...
herdsize = 30
herd = []
for i in xrange (herdsize)
color, position = function_to_supply_a_gazelle's_attributes()
herd.append (Gazelle (color, position)
# ...
while true:
for gazelle in herd:
do_something_to (gazelle)
