Nov 30, 2016 · 14. Easy, use sequence multiplication: arr = bytearray(b'\x01') * 10 ** 9. Same approach works for initializing with zeroes (bytearray(b'\x00') * 10 ** 9), and it's generally preferred, since passing integers to the bytes constructor has been a source of confusion before (people sometimes think they can make a single element bytes with the ...

If the concepts of an object being “mutable” and “immutable” is not ...
Jul 8, 2021 · Output: The string is: pythonforbeginners.com The bytearray object is: bytearray (b'pythonforbeginners.com') We can convert a list of integers to bytearray using bytearray () function in python. The bytearray () function takes the list of integers between 0 and 255 as input and returns the corresponding bytearray object as follows.
