In this example we can see that every element is OR by the value that is passed as a parameter in MaskedArray.__ior__() method.




# import the important module in python 
import numpy as np 
      
# make an array with numpy 
gfg = np.ma.array([1, 2, 3, 4, 5]) 
      
# applying MaskedArray.__ior__() method 
print(gfg.__ior__(2)) 
  
Output:
[3 2 3 6 7]

 
Example #2:




# import the important module in python 
import numpy as np 
      
# make an array with numpy 
gfg = np.ma.array([[1, 2, 3, 4, 5], 
                [6, 5, 4, 3, 2]]) 
      
# applying MaskedArray.__ior__() method
