You caught me!  :)  This is actually my first python code ever, but 
that's not an excuse to have missed this.  That last line should be this:
[ "mac=00:16:ee:%02x:%02x:%02x, bridge=intbr" % tuple([int(i) for i in 
ip.split('.')[1:4]]), ]
That's the prettiest I can do for now.  Thanks for picking this out!
