Importing this module does *not* mark any standard classes as implementing any of these interfaces. While this module is not deprecated, new code should generally use :mod:`zope.interface.common.collections`, specifically :class:`~zope.interface.common.collections.IMapping` and :class:`~zope.interface.common.collections.IMutableMapping`. This module is occasionally useful for its extremely fine grained breakdown of interfaces. The standard library :class:`dict` and :class:`collections.UserDict` implement ``IMutableMapping``, but *do not* implement any of the interfaces in this module. ) Interface) collectionsceZdZdZdZy) IItemMappingz%Simplest readable mapping object cy)z`Get a value for a key A `KeyError` is raised if there is no value for the key.
