Numpy ndarray.tobytes() function | Python

numpy.ndarray.tobytes() function construct Python bytes containing the raw data bytes in the array.

Syntax : numpy.ndarray.tobytes(order=’C’)

Parameters :
order : [{‘C’, ‘F’, None}, optional] Order of the data for multidimensional arrays: C, Fortran, or the same as for the original array.

Return : Python bytes exhibiting a copy of arr’s raw data.

Code #1 :

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

# importing numpy as geek
import numpy as geek

arr = geek.array([[0, 1], [2, 3]], dtype ='<u2')

gfg = arr.tobytes()

print (gfg)

Output :

b'\x00\x00\x01\x00\x02\x00\x03\x00'

Code #2 :

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

# importing numpy as geek

arr = geek.array([[0, 1], [2, 3]], dtype ='<u2')

gfg = arr.tobytes('F')

print (gfg)

Output :

b'\x00\x00\x02\x00\x01\x00\x03\x00'
