Python program to convert byte array back to NumPy array# Import numpy import numpy as np # Creating a numpy array arr = np.arange(8*8).reshape(8, 8) # Display original array print("Original Array:\n",arr,"\n") # Converting array into byte array by = arr.tobytes() # Converting...
Many different types of data objects are supported by Python. Two of them are the objects bytearray and bytes. This article will describe these functions and explain how bytearray objects can be converted into bytes objects.

5. Convert Bytes Array to String To convert a byte array to a string, you can use thebytes()constructor to create a bytes object from the array, and then use thedecode()method to convert the bytes object to a string. # Create a byte arraybyte_array=bytearray([115,112,97,114,107]...
Python supports different types of sequence objects to store data. One such object is a bytearray object. As the name suggests, a bytearray object is an array
The `binascii` module in Python provides several utility functions for converting binary data to different representations including hexadecimal. The `binascii.hexlify()` function can be used to convert a bytearray to a hexadecimal string. Example Open Compiler byte_array = bytearray(b'Hello, worl...
The easiest way to convert a list to an array is to use the array() function from the array module in Python. The array() function creates an array of specified type and size from a Python list.Following is the code to convert a list to an array using the array() function:...
