numpy.ma.filled() function - Python

numpy.ma.filled() function return input as an array with masked data replaced by a fill value. If arr is not a MaskedArray, arr itself is returned. If arr is a MaskedArray and fill_value is None, fill_value is set to arr.fill_value.

Syntax : numpy.ma.filled(arr, fill_value = None)

Parameters :
arr : [MaskedArray or array_like] An input object.
fill_value : [scalar, optional] Filling value. Default is None.

Return : [ndarray] The filled array.

Code #1 :

# Python program explaining 
# numpy.ma.filled() function 
    
# importing numpy as geek    
# and numpy.ma module as ma   
import numpy as geek   
import numpy.ma as ma 
   
arr = geek.ma.array(geek.arange(4).reshape(2, 2), 
                         mask =[[1, 0], [0, 1]]) 
  
gfg = arr.filled() 
  
print (gfg) 

Output :

[[999999      1]
 [     2 999999]]

Code #2 :

# Python program explaining 
# numpy.ma.filled() function 
    
# importing numpy as geek    
# and numpy.ma module as ma   
import numpy as geek   
import numpy.ma as ma 
   
arr = geek.ma.array(geek.arange(9).reshape(3, 3),  
          mask =[[1, 0, 0], [1, 0, 0], [0, 0, 0]]) 
  
gfg = arr.filled() 
  
print (gfg) 

Output :

[[999999      1      2]
 [999999      4      5]
 [     6      7      8]]
