difference()	                -	        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()	 	                        Remove the specified item
intersection()	                &	        Returns a set, that is the intersection of two other sets

isdisjoint()	 	                        Returns whether two sets have a intersection or not

 	                        <	        Returns True if all items of this set is present in another, larger set

symmetric_difference()	        ^	        Returns a set with the symmetric differences of two sets

union()	                        |	        Return a set containing the union of sets
