Python NumPy: Find the union of two arrays

Python NumPy: Array Object Exercise-22 with Solution

Write a Python program to find the union of two arrays. Union will return the unique, sorted array of values that are in either of the two input arrays.

Sample Solution:-

Python Code:

import numpy as np
array1 = np.array([0, 10, 20, 40, 60, 80])
print("Array1: ",array1)
array2 = [10, 30, 40, 50, 70]
print("Array2: ",array2)
print("Unique sorted array of values that are in either of the two input arrays:")
print(np.union1d(array1, array2))

Sample Output:

Array1:  [ 0 10 20 40 60 80]                                           
Array2:  [10, 30, 40, 50, 70]                                          
Unique sorted array of values that are in either of the two input array
s:                                                                     
[ 0 10 20 30 40 50 60 70 80]

Python Code Editor:

import numpy as np
array1 = np.array([0, 10, 20, 40, 60, 80])
print("Array1: ",array1)
array2 = [10, 30, 40, 50, 70]
print("Array2: ",array2)
print("Unique sorted array of values that are in either of the two input arrays:")
print(np.union1d(array1, array2))
