Python | numpy.ma.ids() method
  • Last Updated : 03 Oct, 2019

With the help of numpy.ma.ids() method, we can get the address of masked array having data by using numpy.ma.ids() method.

Syntax : numpy.ma.ids(array, mask)
Return : Return the address of masked array.

Example #1 :
In this example we can see that by using numpy.ma.ids() method, we are able to get the address of the targeted masked array.




# import numpy.ma
import numpy.ma as ma
  
# using numpy.ma.ids() method
gfg = ma.array([1, 2, 4, 8], mask =[1, 0, 0, 1])
  
print(gfg.ids())

Output :

(2172543392448, 2172542026240)



Example #2 :




# import numpy.ma
import numpy.ma as ma
  
# using numpy.ma.ids() method
gfg = ma.array([[1, 2, 3], [4, 5, 6], [7, 8, 9]], 
         mask =[[1, 0, 0], [0, 1, 0], [0, 0, 1]])
  
print(gfg.ids())
print(gfg)

Output :

(2172299359856, 2172543392224)

masked_array(
data=[[–, 2, 3],
[4, –, 6],
[7, 8, –]],
mask=[[ True, False, False],
[False, True, False],
[False, False, True]],
fill_value=999999)
