I have heard that when you perform an in operator on a list it has to search through O(n) objects while if you do it on a set it has to search through O(1) objects. To see what I mean go here. Does this still apply to OrderedSet?
Does OrderedSet() still have a search parameter of O(1)?

Which
OrderedSetare you talking about? At this time (Python 3.8.3), there is notOrderedSetin the standard library.Typically, OrderedSet implementations will implement
__contains__by delegating to the underlyingset. So it will have the algorithmic complexity you would expect.
