Python programming language is very easy to learn for students and professionals.
A set is a collection of unique data. That is, elements of a set cannot be duplicate.
Create a Set in Python
In Python, we create sets by placing all the elements inside curly braces {}, separated by comma.
A set can have any number of items and they may be of different types (integer, float, tuple, string etc.).
But a set cannot have mutable elements like lists, sets or dictionaries as its elements.
Create an Empty Set in Python
Creating an empty set is a bit tricky. Empty curly braces {} will make an empty dictionary in Python.
Add Set Items in Python
Sets are mutable. However, since they are unordered, indexing has no meaning.
We cannot access or change an element of a set using indexing or slicing.
we use the add() method to add an item to a set.
Remove an Element from a Set
We use the discard() method to remove the specified element from a set.
Iterate Over a Set in Python
using for loop
Find Number of Set Elements
