There are four main set operations that allow you to compare and contrast collections like a Venn Diagram. Union and Intersection are two methods for comparing shared membership between sets.

#### Main Set Operations

The following methods and operations return a new set.

`s.intersection(t)`

/ `s & t`

- Return the intersection of two sets as a new set. (i.e. all elements that are in both sets.)

`s.union(t)`

/ `s | t`

- Return the union of sets as a new set. (i.e. all elements that are in either set.)
