Python 2 to 3 Conversion

[Wildman]

Thanks to Chris and Ben.  Your suggestions were slightly
different but both worked equally well, although I don't
understand how that can be so.

> struct.pack('256s', ifname[:15].encode('ascii'))
> struct.pack('256s', ifname.encode('ascii'))

I was looking for a reliable way to determine the IP addy
for a given network adapter.  That is what the code does
but I don't understand how it does it either.

Thanks again.  I will continue to research and study the
code in the hope I will understand it.
