Subsequent uses return the\nresults of the first call. They come handy when code should run\n\n- *late*, i.e. just before it is needed, and\n- *once*, i.e. not twice, in the lifetime of an object.\n\nYou can think of it as *deferred initialization*.\nThe possibilities are endless.\n\nExamples\n========\n\nThe class below creates its ``store`` resource lazily::\n\n    from lazy import lazy\n\n    class FileUploadTmpStore(object):\n\n        @lazy\n        def store(self):\n            location = settings.get('fs.filestore')\n            return FileSystemStore(location)\n\n        def put(self, uid, fp):\n            self.store.put(uid, fp)\n            fp.seek(0)\n\n        def get(self, uid, default=None):\n            return self.store.get(uid, default)\n\nAnother application area is caching::\n\n    class PersonView(View):\n\n        @lazy\n        def person_id(self):\n            return self.request.get('person_id', -1)\n\n        @lazy\n        def person_data(self):\n            return self.session.query(Person).get(self.person_id)\n\nDocumentation\n=============\n\nFor further details please refer to the `API Documentation`_.\n\n.. _`API Documentation`: https://lazy.readthedocs.io/en/stable/\n\nCredits\n=======\n\nI first encountered this type of descriptor in the\n``zope.cachedescriptors`` package, which is part of the\n`Zope Toolkit`_.\n\n.. _`Zope Toolkit`: https://zopetoolkit.readthedocs.io\n\n\nChangelog\n=========\n\n1.4 - 2019-01-28\n----------------\n\n- Add MANIFEST.in.\n  [stefan]\n\n- Release as universal wheel.\n  [stefan]\n\n1.3 - 2017-02-05\n----------------\n\n- Support Python 2.6-3.6 without 2to3.\n  [stefan]\n\n- Add a LICENSE file.\n  [stefan]\n\n1.2 - 2014-04-19\n----------------\n\n- Remove setuptools from install_requires because it isn't.\n  [stefan]\n\n1.1 - 2012-10-12\n----------------\n\n- Use ``functools.wraps()`` properly; the list of attributes changes with\n  every version of Python 3.\n  [stefan]\n\n1.0 - 2011-03-24\n----------------\n\n- Initial release.\n",
