- 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.
- It is designed to be used as follows::
- from __future__ import (absolute_import, division,
- print_function, unicode_literals)
- from builtins import (
- bytes, dict, int, list, object, 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
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- ``future`` supports the standard library reorganization (PEP 3108) through the
- following Py3 interfaces:
- >>> # Top-level packages with Py3 names provided on Py2:
- >>> import html.parser
- >>> import queue
- >>> import tkinter.dialog
- >>> import xmlrpc.client
- >>> # etc.
- >>> # Aliases provided for extensions to existing Py2 module names:
- >>> from future.standard_library import install_aliases
- >>> install_aliases()
- >>> from collections import Counter, OrderedDict # backported to Py2.6
- >>> from collections import UserDict, UserList, UserString
- >>> import urllib.request
- >>> from itertools import filterfalse, zip_longest
- >>> from subprocess import getoutput, getstatusoutput
- 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``.
