numpy.ma.is_masked() function determine whether input has masked values & accepts any object as input, but always returns False unless the input is a MaskedArray containing masked values.
Syntax : numpy.ma.is_masked(arr)
Parameters :
arr : [array_like] Array to check for masked values.Return : [bool] True if arr is a MaskedArray with masked values, False otherwise.
Code #1 :
# Python program explaining # numpy.ma.is_masked() function # importing numpy as geek # and numpy.ma module as ma import numpy as geek import numpy.ma as ma arr = ma.masked_equal([0, 1, 2, 0, 3], 0) gfg = ma.is_masked(arr) print (gfg) |
Output :
True
Code #2 :
# Python program explaining # numpy.ma.is_masked() function # importing numpy as geek # and numpy.ma module as ma import numpy as geek import numpy.ma as ma arr = [True, False, True] # always returns False unless # the input is a MaskedArray gfg = ma.is_masked(arr) print (gfg) |
Output :
False
