About
========

:class:`~cawdrey.nonelessdict.NonelessDict` is a wrapper around dict that will check if a value is :py:obj:`None`/empty/:py:obj:`False`, and not add the key in that case.

The class has a method :meth:`~cawdrey.nonelessdict.NonelessDict.set_with_strict_none_check` that can be used to set a value and check only for ``None`` values.

:class:`~cawdrey.nonelessdict.NonelessOrderedDict` is based on :class:`~cawdrey.nonelessdict.NonelessDict` and :class:`~collections.OrderedDict`, so the order of key insertion is preserved.
