When you print bytes, Python doesn't use "hexadecimal notation."  It 
prints a Python bytes literal.  That literal will use printable 
characters like 'Q', or hex escapes like '\x00', or other escapes like 
'\n', depending on the character.   If you want hex output, you have to 
create it yourself, for example with the binascii module.
