Python 3.x and bytes

In Python 3 one can say --> huh = bytes(5) Since the bytes type is actually a list of integers, I would have expected this to have huh being a bytestring with one element -- the integer 5. Actually, what you get is: --> huh b'\x00\x00\x00\x00\x00' or five null bytes. Note that this is an
