I need a data type that will allow me to effectively track objects that have been “added” to it, which allows me to test membership. I do not need other functions.
As far as I can tell, Python doesn't have that kind of data. Closest to what I want is Set, but the set will always store values (which I don't need).
For now, the best I can think of is to take hash()each object and store it in a set, but at a lower level, the hash hash is computed and the hash string is stored as a value.
Is there a way to use only low-level set search functions without actually pointing to anything?
