*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``
(compare the elements directly).
key from each element in *iterable* (for example, ``key=str.lower``). The
default value is ``None`` (compare the elements directly).
*reverse* is a boolean value. If set to ``True``, then the list elements are
sorted as if each comparison were reversed.

``key=str.lower`` Equivalent to: ``sorted(iterable, key=key,

The latter two functions perform best for smaller values of *n*. For larger
