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. i(tdivisiontabsolute_importtprint_functionN(tutils(tnewrangetfiltertmaptrangetzip(t__doc__t __future__RRRt itertoolstfutureRtPY3tifilterRtimapRt future.typesRRtizipRt__all__tbuiltins(((s8lib/python2.7/site-packages/future/builtins/iterators.pyt!s
