Python’s bytearray is a mutable sequence of bytes that allows you to manipulate binary data efficiently. Unlike immutable bytes, bytearray can be modified in place, making it suitable for tasks requiring frequent updates to byte sequences. You can create a bytearray using the bytearray() constructor with various arguments or from a string of hexadecimal digits using .fromhex(). This tutorial explores creating, modifying, and using bytearray objects in Python. You’ll dive deeper into each aspect of bytearray, exploring its creation, manipulation, […]
