ByteArray is a data structure in Python that can be used when we wish to store a collection of bytes in an ordered manner in a contiguous area of memory. ByteArray comes under binary data types. You can use the bytearray() constructor to create a ByteArray object as shown below >>> ...

Write a Python program to create a bytearray from a list. Sample Solution: Code: # Print a blank line for separation.print()# Create a list of integers called nums.nums=[10,20,56,35,17,99]# Create a bytearray from the list of integers.values=bytearray(nums)# Iterate through the el...

Return an array of 4 bytes: x = bytes(4) Try it Yourself » Definition and Usage Thebytes()function returns a bytes object. It can convert objects into bytes objects, or create empty bytes object of the specified size. The difference betweenbytes()andbytearray()is thatbytes()returns an...
