# Built-In Function: Union, Intersection, and dynamic execution

Learn about union, intersection, and dynamic execution in Powershell and Python.

## We'll cover the following

## Union and Intersection

The **union** of two or more sets is the set of all distinct elements present in all constituent sets. The intersection of given sets consists of all the elements which are common to all the constituent sets. In Python, we can perform these operations on a set which is a list of unique items enclosed in curly braces { }. All set objects have inbuilt functions `union()`

or `intersection()`

.
