The future module helps run Python 3.x-compatible code under Python 2 with minimal code cruft.
The goal is to allow you to write clean, modern, forward-compatible Python 3 code today and to run it with minimal effort under Python 2 alongside a Python 2 stack that may contain dependencies that have not yet been ported to Python 3.
It is designed to be used as follows:
from __future__ import (division, absolute_import, print_function,
unicode_literals)
from future import *
followed by clean Python 3 code (with a few restrictions) that can run unchanged on Python 2.7.
For example:
# Supports the standard library reorganization (PEP 3108)
import socketserver
import queue
import configparser
# and other moved modules
# New range object with slicing support
for i in range(10**11)[:10]:
pass
# Other common iterators: map, reduce, zip
my_iter = zip(range(3), ['a', 'b', 'c'])
assert iter != list(my_iter)
# New simpler super() function:
class VerboseList(list):
def append(self, item):
print('Adding an item')
super().append(item)
# These raise NameErrors:
# apply(), cmp(), coerce(), reduce(), xrange(), etc.
# This identity is restored. This is normally valid on Py3 and Py2, but
# 'from __future__ import unicode_literals' breaks it on Py2:
assert isinstance('happy', str)
