# Python Set intersection example :

*Intersection* is used to find out the common elements between two Sets. Symbol *‘∩’* is used to denote intersection.

For example :

In the above example, we have two Set *A* and *B* and we are finding out the intersection between them *A∩B*. The intersection is the common elements between *A* and *B*.

From the above example, it is clear that *A∩B = B∩C*.

## Finding intersection in Python :

Python comes with an inbuilt method *intersection()* to find out the intersection between two or more sets. In this blog post, we will show you how to use *intersection()* to find out the intersection between multiple sets in python. The syntax of the *intersection()* method is as below :

s.intersection(*t)

*It will find the intersection between set s and one or multiple sets. It returns the final set.*

### Example :

Let’s try to implement it with an example (You can find the source code on Github ) :

As you can see, the first two times we have to find out the intersection between two sets but last time we have calculated the intersection between three sets.

### Conclusion :

*intersection()* is really a useful method to find out the intersection between sets in python. Try to implement the example we have shown above and drop one comment below if you have any queries.
