Well, not quite -- there seems to be some tuple-vs-lits confusions in
your text vs your code, as well as some confusion as to what gets added
to what else.  But I think what you want is, roughly:

    Wire = ('GW', wires) + wirelist[wires]

i.e., you want to CONCATENATE the wirelist[wires] tuple right after
the two-items tuple whose first item is 'GW' and whose second item
is wires.  Python does express sequence concatenation as 'adding'
(i.e., it uses the plus sign to indicate it).
