In python-2.4, a builtin :class:`set` type was added to python.  This
module
provides a function to emulate that on python-2.3 by using the :mod:`sets`
module.

:func:`set`
    Create a set.  If running on python 2.4+ this is the :class:`set`
    constructor.  If using python-2.3, it's :class:`sets.Set`.

:func:`frozenset`
    Create a frozenset.  If running on python2.4+ this is the
    :class:`frozenset` constructor.  If using python-2.3, it's
    :class:`sets.ImmutableSet`.

there's no set builtin, us the :mod:`sets` module to make one

    This function makes sure that a :class:`set` and :class:`frozenset`
type
    are available in the :mod:`__builtin__` namespace.  Since the function
    checks whether :class:`set` and :class:`frozenset` are already present
in
    the :mod:`__builtin__` namespace and refuses to overwrite those if
found,
    it's safe to call this in multiple places and in scripts run under
    python-2.4+, where a more efficient set implementation is already
present
    in the :mod:`__builtin__` namespace.

    However, since this function modifies :mod:`__builtin__` there's
no need
    to call it more than once  so you likely want to do something like this
    when your program loads::

        myprogram/__init__.py:

        from kitchen.pycompat24 import sets
        builtinset.add_builtin_set()

    You can then use :func:`set` and :func:`frozenset` anywhere in your
code::

        myprogram/compute.py:

        def math_students(algebra_student_list, geometry_student_list):
            return set(algebra_student_list) union
set(geometry_student_list)
