numpy.ndarray.getfield() function return a field of the given array as a certain type.

Syntax : numpy.ndarray.getfield(dtype, offset=0)

Parameters :
dtype : [str or dtype] The dtype size of the view can not be larger than that of the array itself.
offset : [int] Number of bytes to skip before beginning the element view.

Return : Returns a field of the given array as a certain type.

Code #1 :

# Python program explaining
# numpy.ndarray.getfield() function

# importing numpy as geek
import numpy as geek

x = geek.diag([1.+1.j]*2)

gfg = x.getfield(geek.float64)

print(gfg)

Output :

[[ 1.  0.]
 [ 0.  1.]]

Code #2 :

# Python program explaining
# numpy.ndarray.getfield() function

# importing numpy as geek
import numpy as geek

x = geek.diag([2.+2.j]*2)

gfg = x.getfield(geek.float64, offset = 8)

print(gfg)

Output :

[[ 2.  0.]
 [ 0.  2.]]
