Python 3 Basics # 17.1 | Sets in Python | What is a Python Set | Immutable vs Hashable
Python built-in type set has the following characteristics:
Set are unordered.
Set elements are unique and it doesn’t allow duplicate elements.
Set itself may be modified but the elements contained in the set must be Hashable.

Objects that cannot be changed after its created is called immutable object.
Object on which hash function works is called Hashable Object.

In python any immutable object (such as integer, boolean, string, tuple is Hashable which means its value doesn’t change during its lifetime. This allows Python to create a unique hash value to identify it, which can be used by dictionaries to track unique keys and which in turn helps to track unique values.
