How to find the intersection between two Numpy arrays?
In this problem, we will find the intersection between two numpy arrays. The intersection of two arrays is an array that has elements in common in both original arrays
Step 1 : Import numpy. Step 2 : Define two numpy arrays. Step 3 : Find intersection between the arrays using the numpy.intersect1d() function. Step 4 : Print the array of intersecting elements.
import numpy as np array_1 = np.array([1,2,3,4,5]) print( "Array 1:\n" , array_1) array_2 = np.array([2,4,6,8,10]) print( "\nArray 2:\n" , array_2) intersection = np.intersect1d(array_1, array_2) print( "\nThe intersection between the two arrays is:\n" , intersection)
Array 1: [1 2 3 4 5 ] Array 2: [2 4 6 8 10 ] The intersection between the two arrays is: [twenty four ]
