Using Python 3 compatible print statements in snippets (firebase#157) (firebase#159)
* Uses python 3 compatible print statements. * Fixed Python 3 incompatible print syntax used in snippets. * adjusting snippets to lint happily on Python <3 - added "from __future__ import print_function" in snippets using print to make pylint "print-function-aware" and lint Python 3.x print-syntax without errors when running under Python 2.x. * remove unwanted parens from print statements in snippets - delete duplicate parens added in previous commits * Uses python 3 compatible print statements. * Fixed Python 3 incompatible print syntax used in snippets. - added "from __future__ import print_function" in snippets using print to make pylint "print-function-aware" and lint Python 3.x print-syntax without errors when running under Python 2.x. - delete duplicate parens used in print statements
