How to port bytes formatting to Python 3.x ?

[Baptiste Lepilleur]

Hi,
I'm trying to port a small library to Python 3.x, and I'm wondering what is
the best way to port statements such as the one belows that are  frequently
found in network protocol implementation:

        headerparts = ("%s:%s\n" % (key, value) for key, value in
headers.iteritems())
        framebytes = "%s\n%s\n%s\x00" % (command, "".join(headerparts),
body)

Where all manipulated string are actually bytes, though value in headers
dict may be any objects.

Baptiste.
