Set Theory Operations

The mathematical definition of sets assigns some inherent properties to sets, such as element uniqueness and unorderedness. It also specifies the operations allowed, such as union, intersection, difference, and symmetric difference. Python supports all of these, as we’ll now see.

Unique elements

In Python, sets are used to store unique elements. Adding duplicate elements to a set will automatically remove the duplicates and only store one instance of each element. Let's see an example.
