numpy.ma.clump_masked() function | Python

numpy.ma.clump_masked() function returns a list of slices corresponding to the masked clumps of a 1-D array.

Syntax : numpy.ma.clump_masked(arr)

Parameters :
arr : [ndarray] A one-dimensional masked array.

Return : [list of slice] The list of slices, one for each continuous region of masked elements in arr.

Code #1 :

# Python program explaining
# numpy.ma.clump_masked() function

# importing numpy as geek
# and numpy.ma module as ma
import numpy as geek
import numpy.ma as ma

arr = geek.ma.masked_array(geek.arange(8))
arr[[0, 1, 2, 6]] = geek.ma.masked

gfg = geek.ma.clump_masked(arr)

print (gfg)

Output :

[slice(0, 3, None), slice(6, 7, None)]

Code #2 :
