The 'sep="\n"' parameter to print() means "put a newline between each 
item."  So don't do that.  Put the newlines you do want in explicitly, 
or use separate calls to print():

(I'm abbreviating because I really can't be bothered to type that much :-)

   print("X:", thing[0],
         "\nY:", thing[1],
         "\nZ:", thing[2],
         file=outstream)

or

   print("X:", thing[0], file=outstream)
   print("Y:", thing[1], file=outstream)
   print("Z:", thing[2], file=outstream)

I would probably use the latter, but it's just a matter of personal 
preference.

(Actually I would probably use outstream.write() and do my own 
formatting, but let's not get side-tracked ;-)
