The difference() method returns a set that contains the difference between two sets. Meaning: The returned set contains items that exist only in the first set, and not in both sets. As a shortcut, you can use the -operator instead, see example below.
With .difference you can do things like: s1 = set([1,2,3]) print(s1.difference(*[[3],[4],[5]])) {1, 2} It is also more efficient when creating sets using the *(iterable,iterable) syntax as you don't create intermediary sets, you can see some comparisons here
Learn how to use the difference() method to compute the difference of two sets and return items that are unique to the first set. See syntax, parameter, return value and examples of the difference() method and the - operator.
Learn how to use the set difference () method or set difference operator (-) to find the difference between two or more sets in Python. See the difference between the set difference () method and the set difference operator, and how to use them with iterables.

The Python Set difference() method is used with sets to return a new set containing elements that are present in the first set but not in any of the other sets provided as arguments. It effectively performs a subtraction operation on sets removing elements that appear in the subsequent sets.
