""" future: Easy, safe support for Python 3/2 compatibility ======================================================= ``future`` is the missing compatibility layer between Python 3 and Python 2. It allows you to use a single, clean Python 3.x-compatible codebase to support both Python 3 and Python 2 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.builtins import (bytes, dict, int, range, str, ascii, chr, hex, input, next, oct, open, pow, round, super, filter, map, zip) followed by predominantly standard, idiomatic Python 3 code that then runs similarly on Python 2.6/2.7 and Python 3.3+. The imports have no effect on Python 3. On Python 2, they shadow the corresponding builtins, which normally have different semantics on Python 3 versus 2, to provide their Python 3 semantics. Standard library reorganization ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ``from future import standard_library`` provides a context-manager called ``hooks`` that installs import hooks (PEP 3108) to allow renamed and moved standard library modules to be imported from their new Py3 locations. 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``.
