## 30 Mar Intersection of Numpy Arrays

If you want to get the intersection of two arrays, use the intersect1d() method in Numpy. Intersection means finding common elements between two arrays. In this lesson, we will see some examples:

• Find the intersection between two arrays
• Finding intersection sorts the resultant array
• Find the intersection between two arrays with different elements

## Find the intersection between two arrays

The intersect1d() method finds the intersection between two arrays. Let us see an example. We have created two integer arrays. We will find the intersection between these arrays:

Output

## Finding intersection sorts the resultant array

The intersect1d() method finds the intersection and also sorts the result. Let us see an example. We have created two unsorted integer arrays. We will find the intersection between these arrays that will display a sorted result:

Output

## Find the intersection between two arrays with different elements

Let us see what will happen when we find the intersection between two arrays with different elements. Therefore, both the arrays do not have even a single element similar.

Let us see the result:
