Formula
Python has a set of built - in methods that you can use on sets.Removes all the elements from the set copy()
Returns a set containing the difference between two or more sets difference_update() -= Removes the items in this set that are also included in another, specified set discard()
& Returns a set, that is the intersection of two other sets intersection_update() &= Removes the items in this set that are not present in other, specified set(s) isdisjoint() Returns whether two sets have a intersection or not issubset() <= Returns True if all items of this set is present in another set < Returns True if all items of this set is present in another, larger set issuperset() >= Returns True if all items of another set is present in this set > Returns True if all items of another, smaller set is present in this set pop()
Removes the specified element symmetric_difference() ^ Returns a set with the symmetric differences of two sets symmetric_difference_update() ^= Inserts the symmetric differences from this set and another union() | Return a set containing the union of sets update() |= Update the set with the union of this set and others
