Return a new sorted list from the items in *iterable*.

+ The optional arguments *key* and *reverse* have the same meaning as
those for the :meth:`list.sort` method (described in section
:ref:`typesseq-mutable`).
- *cmp* specifies a custom comparison function of two arguments (iterable
- elements) which should return a negative, zero or positive number depending on
- whether the first argument is considered smaller than, equal to, or larger than
- the second argument: ``cmp=lambda x,y: cmp(x.lower(), y.lower())``. The default
- value is ``None``.
-
*key* specifies a function of one argument that is used to extract a comparison
key from each list element: ``key=str.lower``. The default value is ``None``.
*reverse* is a boolean value. If set to ``True``, then the list elements are
sorted as if each comparison were reversed.
- In general, the *key* and *reverse* conversion processes are much faster than
- specifying an equivalent *cmp* function. This is because *cmp* is called
- multiple times for each list element while *key* and *reverse* touch each
- element only once.
