* :class:`dict` methods :meth:`dict.keys`, :meth:`dict.items` and
:meth:`dict.values` return "views" instead of lists. For example,
this no longer works: ``k = d.keys(); k.sort()``. Use ``k =
- sorted(d)`` instead (this works in Python 2.5 too, and is just
+ sorted(d)`` instead (this works in Python 2.5 too and is just
as efficient).
* Also, the :meth:`dict.iterkeys`, :meth:`dict.iteritems` and
* New binary literals, e.g. ``0b1010`` (already in 2.6).
-* Bytes literals are introduced with a leading ``b`` or ``B``.
+* Bytes literals are introduced with a leading ``b`` or ``B``, and
+ there is a new corresponding builtin function, :func:`bin`.
Changed Syntax
--------------
:mod:`collections` module plays a somewhat more prominent role in
the language now, and builtin collection types like :class:`dict`
and :class:`list` conform to the :class:`collections.MutableMapping`
- and :class:`collections.MutableSequence` ABC, respectively.
+ and :class:`collections.MutableSequence` ABCs, respectively.
* :ref:`pep-3127`. As mentioned above, the new octal literal
notation is the only one supported, and binary literals have been
