This module exposes several standard library modules to Python 2 under their new Python 3 names. It is designed to be used as follows:: from future import standard_library standard_library.install_aliases() And then these normal Py3 imports work on both Py3 and Py2:: import builtins import copyreg import queue import reprlib import socketserver import winreg # on Windows only import test.support import html, html.parser, html.entites import http, http.client, http.server import http.cookies, http.cookiejar import urllib.parse, urllib.request, urllib.response, urllib.error, urllib.robotparser import xmlrpc.client, xmlrpc.server import _thread import _dummy_thread import _markupbase from itertools import filterfalse, zip_longest from sys import intern from collections import UserDict, UserList, UserString from collections import OrderedDict, Counter, ChainMap # even on Py2.6 from subprocess import getoutput, getstatusoutput from subprocess import check_output # even on Py2.6 (The renamed modules and functions are still available under their old names on Python 2.) This is a cleaner alternative to this idiom (see http://docs.pythonsprints.com/python3_porting/py-porting.html):: try: import queue except ImportError: import Queue as queue Limitations ----------- We don't currently support these modules, but would like to:: import dbm import dbm.dumb import dbm.gnu import collections.abc # on Py33 import pickle # should (optionally) bring in cPickle on Python 2 � )�absolute_import�division�print_functionNZ future_stdlib)�PY2�PY3)�test�urllib�pickle�dbm�builtins�copyreg�queue� socketserverZ configparser�reprlib�winreg�_thread)� � � _dummy_thread�xmlrpc�html�http� _markupbase) � __builtin__Zcopy_regZQueuezfuture.moves.socketserverZ ConfigParser�reprZ_winreg�threadZ dummy_threadzfuture.moves.xmlrpczfuture.moves.htmlzfuture.moves.httpzfuture.moves._markupbase))� collections�UserListr r )r �UserDictr r )r � UserStringr r �r �ChainMap�future.backports.miscr! )� itertools� filterfalser# Z ifilterfalse)r# � zip_longestr# Z izip_longest)�sys�internr r' )�re�ASCII�stat�ST_MODE)�base64Z encodebytesr, Z encodestring)r, Z decodebytesr, Z decodestring)� subprocess� getoutput�commandsr. )r- �getstatusoutputr/ r0 )r- � check_outputr" r1 )Zmath�ceilr" r2 )r � OrderedDictr" r3 )r �Counterr" r4 r )r# �countr" r5 )r �recursive_reprr" r6 )� functools� cmp_to_keyr" r8 c @ s8 e Zd ZdZdZdd� Zd dd�Zdd � Zd d d �ZdS )� RenameImportzX A class for import hooks mapping Py3 module names etc. to the Py2 equivalents.

Saves the state of sys.modules and restores it after the 'with' block. Use like this: >>> from future import standard_library >>> with standard_library.hooks(): ... import http.client >>> import requests For this to work, http.client will be scrubbed from sys.modules after the 'with' block. That way the modules imported in the 'with' block will continue to be accessible in the current namespace but not from any imported modules (like requests). c C s t � tj�| _t� | _t� | S r: )�copyr& rS �old_sys_modules� detect_hooks�hooks_were_installed� install_hooks�rJ r; r; r? � __enter__A s zhooks.__enter__c G s | j s t� d S r: )rk � remove_hooks�rJ �argsr; r; r? �__exit__I s zhooks.__exit__N�rb rc rd re rn rr r; r; r; r? rg 0 s rg c C s� t rdS dtjvrXtjtjtjg}dd� |D �}tt|��dksNt � d| � |d t_ | j t jv rhdS t| d �r�tj�| j�}|d �tj �r�d |d vr�dS dS ) z� Tries to infer whether the module m is from the Python 2 standard library.
