There's the clue:

In python 3.X, print is a function call
  print(tn.read_all() )
with lots of formatting and line-ending features

In python 2.X, print is a statement:
   print tn.read_all()

If you want one script to work for both Windows and Linux, then you 
should probably
be running the same version of Python on each.   At least both versions 
should be on
the same side for the Python 2.x/3.x version change.
