# 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:
[slice(3, 6, None), slice(7, 8, None)]
