SET

Description

The set operator converts a list to a set (in the Python sense).

Example removing Duplicates

list(set([1, 1, 1]))

Returns [1] since a set cannot contain duplicates

Example to speed-up Rules

large_list := set([87, 737, ..., 1])
42 in large_list

will evaluate much faster than directly doing in on the list, since a set can check if something is part of it in O(1) (see Big O Notation)
