""" future: Easy, safe support for Python 2/3 compatibility ======================================================= ``future`` is the missing compatibility layer between Python 2 and Python 3. It allows you to use a single, clean Python 3.x-compatible codebase to support both Python 2 and Python 3 with minimal overhead. Notable projects that use ``future`` for Python 2/3 compatibility are `Mezzanine <http://mezzanine.jupo.org/>`_ and `xlwt-future <https://pypi.python.org/pypi/xlwt-future>`_. It is designed to be used as follows:: from __future__ import (absolute_import, division, print_function, unicode_literals) from future import standard_library from future.builtins import * # or explicit imports: str, int, bytes, # open, super, range, zip, input, etc. followed by predominantly standard, idiomatic Python 3 code that then runs similarly on Python 2.6/2.7 and Python 3.3+. On Python 3, the import lines have zero effect (and zero namespace pollution). On Python 2, ``from future import standard_library`` installs import hooks to allow renamed and moved standard library modules to be imported from their new Py3 locations. On Python 2, the ``from future.builtins import *`` line shadows all builtins with different behaviour in Python 3 versus 2 to provide their Python 3 semantics. Automatic conversion -------------------- An included script called `futurize <http://python-future.org/automatic_conversion.html>`_ aids in converting code (from either Python 2 or Python 3) to code compatible with both platforms. It is similar to ``python-modernize`` but goes further in providing Python 3 compatibility through the use of the backported types and builtin functions in ``future``.
