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

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

代码#1：

# Python program explaining
# numpy.ma.clump_unmasked() 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_unmasked(arr)
  
print (gfg)

输出 ：
