How to convert array to binary? : Pythoneo

Let’s learn about how to convert array to binary using Numpy Python library.

Using the tofile method

Having an array created you can save it as an binary file using tofile setting bin as your file extension.

import numpy as np

my_array = np.array([1, 3, 5])
my_binary = my_array.tofile("my_binary.bin")
