How to find common part of arrays in Numpy? : Pythoneo

Let’s check how to find common part of arrays in Numpy Python library.

Finding the common part of arrays

To find a common part of arrays just use Numpy intersect1d function. Arrays are parameters of this function.

import numpy as np

my_array = np.array([1, 3, 5, 19, 800, 1154])
my_second_array = np.array([2, 6, 19, 99, 799, 1154])

print(f"my first array: \n{my_array}")
print(f"my second array: \n{my_second_array}")
print(f"common part of arrays: \n{np.intersect1d(my_array, my_second_array)}")
