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``.
