Yes, that way the function will return a list of bytes
instances. Knowing that, consider the following example, that should
ring a bell:

    $ python3
    Python 3.3.2 (v3.3.2:d047928ae3f6, May 16 2013, 09:59:04) 
    [GCC 4.7.2] on linux
    Type "help", "copyright", "credits" or "license" for more information.
    >>> path = b"some/path"
    >>> path.replace('some', '')
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    TypeError: expected bytes, bytearray or buffer compatible object
    >>> path.replace(b'some', b'')
    b'/path'
    >>> 

ciao, lele.
