Set Operations: Symmetric Difference & Difference5:55 with AJ Tran
The other two main set operations are Symmetric Difference and Difference. These methods allow you to contrast the membership of collections.
Main Set Operations
The following methods and operations return a new set.
s - t - Return the difference of two or more sets as a new set. (i.e. all elements that are in this set but not the others.)
s ^ t - Return the symmetric difference of two sets as a new set. (i.e. all elements that are in exactly one of the sets.)
The symmetric difference can also be found with the union minus the intersection:
(s | t) - (s & t)
