<ul data-eligibleForWebStory="true">Sets in Python are a built-in data type that represents an unordered collection of unique elements.Sets are mutable and do not maintain any specific order.Duplicates are automatically removed from sets.Add elements to a set using methods like add() and update().Removing elements using remove() can lead to a KeyError if the element is not present.To safely remove elements, use the discard() method.Set operations like intersection, difference, and symmetric_difference are available.
