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)
