Python is the most flexible language supporting different data structures. Various data structures that Python support are List, Tuple, Dictionary, Set etc. The use of these data structures really makes our work easy. In the previous video we discussed about tuples in Python. Moving further, today we’ll be discussing sets and dictionary in Python.

A set is a collection which is unordered and unindexed. In Python, sets are written with curly brackets. Sets are unordered, so you cannot be sure in which order the items will appear. Once a set is created, you cannot change its items, but you can add new items.

A dictionary is a collection which is unordered, changeable and indexed. In Python dictionaries are written with curly brackets, and they have keys and values.
