    iterable
-      An object capable of returning its members one at a
-      time. Examples of iterables include all sequence types (such as
-      :class:`list`, :class:`str`, and :class:`tuple`) and some non-sequence
-      types like :class:`dict` and :class:`file` and objects of any classes you
-      define with an :meth:`__iter__` or :meth:`__getitem__` method.  Iterables
-      can be used in a :keyword:`for` loop and in many other places where a
-      sequence is needed (:func:`zip`, :func:`map`, ...).  When an iterable
-      object is passed as an argument to the built-in function :func:`iter`, it
-      returns an iterator for the object.  This iterator is good for one pass
-      over the set of values.  When using iterables, it is usually not necessary
-      to call :func:`iter` or deal with iterator objects yourself.  The ``for``
