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.

Python3 1=1

# 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 :

Python3 1=1

# 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)
