Limited Ordered Set object. Data type for storing actions history lists.
Data type for storing sorted list of objects with sort order and list length limit. Useful for storing data like history of user interactions on site.
Once added object to list overflow set length, it pop items from set beginning of set. You always have only last X entries limited b length property.
You can simple install library with pip install limited-ordered-set.
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
