B �A�[t � @ s� d Z ddlmZmZmZ ddlZddlmZ ejs^ej Z ej Z ddl mZ ejZdddd gZn$ddlZej Z ej Z ejZejZg ZdS ) a� This module is designed to be used as follows:: from future.builtins.iterators import * And then, for example:: for i in range(10**15): pass for (a, b) in zip(range(10**15), range(-10**15, 0)): pass Note that this is standard Python 3 code, plus some imports that do nothing on Python 3. The iterators this brings in are:: - ``range`` - ``filter`` - ``map`` - ``zip`` On Python 2, ``range`` is a pure-Python backport of Python 3's ``range`` iterator with slicing support. The other iterators (``filter``, ``map``, ``zip``) are from the ``itertools`` module on Python 2. On Python 3 these are available in the module namespace but not exported for * imports via __all__ (zero no namespace pollution). Note that these are also available in the standard library ``future_builtins`` module on Python 2 -- but not Python 3, so using the standard library version is not portable, nor anywhere near complete. � )�division�absolute_import�print_functionN)�utils)�newrange�filter�map�range�zip)�__doc__� __future__r r r � itertools�futurer �PY3Zifilterr �imapr Z future.typesr r Zizipr �__all__�builtins� r r �J/opt/alt/python37/lib/python3.7/site-packages/future/builtins/iterators.py�<module>! s
