Thanks to all who replied, I hadn't expected pointers to the various
python libraries, for which I am very grateful. All I asked for was a
simple way of directly accessing the hardware, but that does not seem to
be available.

Failing that, I had indeed overlooked the -o flag oo ip a, which indeed
makes parsing easier. However, it does appear that netifaces offers  the
most usable solution, so a cigar to David Wright for this suggestion.

Cheers, Tony
