You can simple install library with

You can add as many as you want objects to LimitedOrderedSet, it will pop first items once items count hit limit.
For example you can go to tests.:
limit = 10 objcts = LimitedOrderedSet(limit) print 'Adding chars: ', for x in xrange(0, 50): c = choice(string.ascii_letters) print c, objcts.add(c) print print 'Resulting set items: %s' % ",".join(objcts)
Adding chars: B Z V N F k j j o v t M k j P v A Y O h E v f A g e F T Q b f r j t W q r C C S m P V m o B z a L w
Resulting set items: S,m,P,V,o,B,z,a,L,w
