Function Details: add

Description

Adds an element to the set.

Extended Description

The add() method adds an element to the set if it's not already present. If the element is already in the set, the method does nothing. The element must be hashable (immutable). Sets only store unique elements, so duplicates are automatically eliminated. This method modifies the set in-place and doesn't return a value.
