This class subclasses the ``Mapping`` ABC, providing a read-only dictionary mapping property names to the corresponding values. Therefore all well-known dicitionary methods and operators (e.g. ``.keys()``, ``.items()``, ``in``) are available to access device properties. Aside of the properties, a device also has a set of udev-specific attributes like the path inside ``sysfs``. :class:`Device` objects compare equal and unequal to other devices and to strings (based on :attr:`device_path`). However, there is no ordering on :class:`Device` objects, and the corresponding operators ``>``, ``<``, ``<=`` and ``>=`` raise :exc:`~exceptions.TypeError`. .. warning:: Never use object identity (``is`` operator) to compare :class:`Device` objects. :mod:`pyudev` may create multiple :class:`Device` objects for the same device. Instead compare devices by value using ``==`` or ``!=``. :class:`Device` objects are hashable and can therefore be used as keys in dictionaries and sets. They can also be given directly as ``udev_device `` to functions wrapped through :mod:`ctypes`. c��C��s$��ddl�}\|jdtdd��tj\|\|�S�)zw .. versionadded:: 0.4 .. deprecated:: 0.18 Use :class:`Devices.from_path` instead. r��Nz>Will be removed in 1.0.
