2. set.clear()

   Removes all elements from a set, leaving it empty

   set.clear()
3. set.copy()

   Creates a shallow copy of a set, returning a new set with the same elements

   set.copy()
4. set.difference_update()

   Removes all elements from this set that are also in another set, modifying the original set in place

   set.difference_update(*others)
5. set.difference()

   Returns a new set containing elements in the calling set but not in the iterables

   set.difference(*others)
6. set.discard()

   Removes an element from a set if it exists, without raising an error if the element is not found

   set.discard(elem)
7. set.intersection()

   Returns a new set containing only elements that exist in all sets

   set.intersection(*others)
8. set.isdisjoint()

   Check if a set has no elements in common with another set

   set.isdisjoint(other)
9. set.issubset()

   Check whether all elements of one set are contained in another set

   set.issubset(other)
10. set.issuperset()

    Check if a set contains all elements of another set

    set.issuperset(other)
11. set.pop()

    Removes and returns an arbitrary element from a set, raising KeyError if the set is empty

    set.pop()
12. set.remove()

    Removes an element from a set, raising KeyError if the element is not found

    set.remove(elem)
13. set.symmetric_difference_update()

    Updates a set in-place with elements in either set but not in both

    set.symmetric_difference_update(other)
14. set.symmetric_difference()

    Returns a new set containing elements in either set but not in both

    set.symmetric_difference(other)
15. set.union()

    Returns a new set containing all elements from multiple sets

    set.union(*others)
16. set.update()

    Adds all elements from one or more iterables to a set, modifying it in place
