Tools: Convert Python 2 syntax to Python 3 compatible

Browse Source 
* The `print """` syntax appears invalid in Python 3 which is the
  default for the Python binary on my system (and soon many more).
* Convert the file (using `2to3`) to a version that's compatible with
  Python 2 and Python 3.
* Tested against Python 2.7.10 and 3.4.3.
