Python set difference() is an inbuilt function that helps us to find the difference between two given sets. It works like a math intersection (A∩B).

Python set difference() is an inbuilt function that helps us to find the difference between two given sets. It works like a math intersection *(A∩B)*. Means, if A and B are two sets, then their difference will be:

**A-B = A-(A∩B)**

**B-A = B-(A∩B)**

The difference() method returns the set difference of two sets. If A and B are two sets. The set difference of A and B is a set of elements that exist only in set A but not in B.

Python sets, and four great operations they provide:

**Intersection**: Elements two sets have in common.**Union**: All the elements from both sets.**Difference**: Elements present on one set, but not on the other.**Symmetric Difference**: Elements from both sets, that are not present on the other.

A set is a collection which is unordered and unindexed. In Python, sets are written with curly brackets.

In this tutorial, you’re going to learn a variety of Python tricks that you can use to write your Python code in a more readable and efficient way like a pro.

In the programming world, Data types play an important role. Each Variable is stored in different data types and responsible for various functions. Python had two different objects, and They are mutable and immutable objects.

Today you're going to learn how to use Python programming in a way that can ultimately save a lot of space on your drive by removing all the duplicates. We gonna use Python OS remove( ) method to remove the duplicates on our drive. Well, that's simple you just call remove ( ) with a parameter of the name of the file you wanna remove done.
