Set in Python

A Set is an unordered collection data type that is iterable, mutable and has no duplicate elements. Python’s set class represents the mathematical notion of a set. The major advantage of using a set, as opposed to a list, is that it has a highly optimized method for checking whether a specific element is contained in the set.

In this article, we will try to a way in which the elements can be removed from the set in a sequential manner. Before going into that let’s learn various characteristics of a set.

Examples

Input : set([12, 10, 13, 15, 8, 9])
Output :
{9, 10, 12, 13, 15}
{10, 12, 13, 15}
{12, 13, 15}
{13, 15}
{15}
set()
