WebPython Sets vs Lists and Tuples. Lists and tuples are standard Python data types that store values in a sequence. Sets are another standard Python data type that also store values. The major difference is that sets, unlike lists or tuples, cannot have multiple occurrences of the same element and store unordered values. WebThere are two settings under which you can get O ( 1) worst-case times. If your setup is static, then FKS hashing will get you worst-case O ( 1) guarantees. But as you indicated, your setting isn't static. If you use Cuckoo hashing, then queries and deletes are O ( 1) worst-case, but insertion is only O ( 1) expected.
