 Let me take you back to your elementary or high school Mathematics lesson. The Mathematics definition of set can be applied also in python. Set is a collection of unordered and unindexed distinct elements. In python set uses to store unique items, and it is possible to find the _union_, _intersection_, _difference_, _symmetric difference_, _subset_, _super set_ and _disjoint set_ among sets.
