Python | Numpy np.mask_or() method

Last Updated : 30 Jan, 2020

With the help of np.mask_or() method, we can combine the two masks with logical OR operator by using np.mask_or() method.

Syntax : np.mask_or(m1, m2) Return : Return the masks with logical OR operator.

Example #1 : In this example we can see that by using np.mask_or() method, we are able to get the two masks with logical OR operator by using this method.

Python3 1=1

# import numpy and mask_or
import numpy as np

m1 = np.array([1, 1, 0, 1])
m2 = np.array([0, 0, 1, 1])

# using np.mask_or() method
gfg = np.ma.mask_or(m1, m2)

print(gfg)

Output :

[True True True True]

Example #2 :

Python3 1=1

# import numpy and mask_or
import numpy as np

m1 = np.array([1, 0, 0, 1, 0])
m2 = np.array([0, 0, 1, 1, 0])

# using np.mask_or() method
gfg = np.ma.mask_or(m1, m2)

print(gfg)

Output :

[True False True True False]
