A set in Python is a data structure that is analogous to a set in mathematics. It can have any number of elements; the order of the elements in a set is undefined. You can add and delete elements from a set, iterate through the set’s elements, and perform standard set operations (union, intersection, difference). Aside from that, you can see if an element is a member of a set.<\/p>\n

In contrast to arrays, where the elements are stored in an ordered list, the order of elements in a set is undefined (moreover, the set elements are usually not stored in order of appearance in the set; this allows checking if an element belongs to a set faster than just going through all the elements of the set).<\/p>\n

Add vs Update in Set<\/h2>\n

In this article, we will look at the main differences between Python’s add() and update() functions for Set.<\/p>\n
