Python Tutorial for Beginners | Sets and Dictionaries in python

Sets and Dictionaries and python.
Elaboration with defination, explaination and examples.
Set in Python is a data structure equivalent to sets in mathematics. It may consist of various elements; the order of elements in a set is undefined. You can add and delete elements of a set, you can iterate the elements of the set, you can perform standard operations on sets (union, intersection, difference).

The dictionary is Python’s built-in mapping type. Dictionaries map keys to values and these key-value pairs provide a useful way to store data in Python.

Typically used to hold data that are related, such as the information contained in an ID or a user profile, dictionaries are constructed with curly braces on either side { }.
