Parameter :
shape : [tuple] Shape of the required MaskedArray.
dtype : [dtype, optional] Data type of the output.Return : [MaskedArray] A masked array with all data masked.
Code #1 :
# Python program explaining # numpy.ma.masked_all() function # importing numpy as geek # and numpy.ma module as ma import numpy as geek
import numpy.ma as ma
gfg = ma.masked_all(( 4 , 4 ))
print (gfg)

Output :
[[-- -- -- --] [-- -- -- --] [-- -- -- --] [-- -- -- --]]
Code #2 :
# Python program explaining # numpy.ma.masked_all() function # importing numpy as geek # and numpy.ma module as ma import numpy as geek
import numpy.ma as ma
gfg = ma.masked_all(( 3 , 3 ), dtype = geek.int32)
print (gfg)

Output :
[[-- -- --] [-- -- --] [-- -- --]]
