Quiz · Dicts and sets · lesson 9 of 11Quiz — set and frozensetWhat is a set, and how does frozenset differ from it?[A]A set can hold any objects, lists and dicts included; frozenset is a set with a fixed size that raises an error when you add more elements than it was created with, and both kinds can still be changed with add and remove after creation.[B]A set is an unordered collection of unique, hashable elements with no indexing or slicing, with fast in checks and the |, &, - operators. set is mutable (add, remove); frozenset is its immutable, hashable twin, usable as a dict key.[C]A set keeps duplicate elements inside and hides them when you loop over it with for; frozenset is the kind that really removes the duplicates, which is why a frozenset can be hashed and used as a dict key or as a set element.[D]A set is an ordered collection that keeps insertion order like a list and allows indexing s[0] and slicing s[1:3]; frozenset differs in that it sorts its elements again, from the smallest to the largest, after each new insertion you make into it.Subscribe to take the courseThe course is free.
