Python Set Methods | Tutorial Reference

How to use Python's built-in set methods like add(), remove(), union(), and difference() to manipulate unordered collections of unique elements efficiently.

In Python, sets are collections of unique elements that are unordered and mutable. They come with several methods that allow you to manipulate and interact with them.

Method	Description
`add()`	Adds an element to the set
`clear()`	Removes all elements from the set
`copy()`	Returns a copy of the set
`difference()`	Returns the difference of two or more sets as a new set
`difference_update()`	Removes all elements of another set from this set
`discard()`	Removes an element from the set if it is a member. (Do nothing if the element is not in set)
`intersection()`	Returns the intersection of two sets as a new set
`intersection_update()`	Updates the set with the intersection of itself and another
`isdisjoint()`	Returns True if two sets have a null intersection
`issubset()`	Returns True if another set contains this set
`issuperset()`	Returns True if this set contains another set
`pop()`	Removes and returns an arbitrary set element. Raises KeyError if the set is empty
`remove()`	Removes an element from the set. If the element is not a member, raises a KeyError
`symmetric_difference()`	Returns the symmetric difference of two sets as a new set
`symmetric_difference_update()`	Updates a set with the symmetric difference of itself and another
`union()`	Returns the union of sets in a new set
`update()`	Updates the set with the union of itself and others
