Python 2.7은 지원이 종료되었으며 2026년 1월 31일에 지원 중단됩니다. 지원 중단 후에는 조직에서 이전에 조직 정책을 사용하여 레거시 런타임의 배포를 다시 사용 설정한 경우에도 Python 2.7 애플리케이션을 배포할 수 없습니다. 기존 Python 2.7 애플리케이션은 지원 중단 날짜 이후에도 계속 실행되고 트래픽을 수신합니다. 지원되는 최신 Python 버전으로 마이그레이션하는 것이 좋습니다.

The version may\n increase even in the absence of user-visible changes to the entity\n group. May return `None`\n if the entity group was never written to.\n\n **Warning** : The behavior of entity group metadata is now different. The entity\n group version can increase independently of user updates. Previously, the entity\n group version increased only on user update. To maintain legacy behavior, use the\n [entity group version workaround](https://support.google.com/cloud/answer/9133787#zippy=python-ndb).\n\n **Arguments**\n\n key\n : key for an entity group.\n\n\nget_namespaces(start=None, end=None)\n\n: Returns a list of namespace names. **Arguments**\n\n start\n : Don't return namespace names before this in alphabetical order.\n\n end\n : Don't return namespace names after this in alphabetical order.\n\nget_kinds(start=None, end=None):\n\n: Returns a list of kind names in the current namespace. **Arguments**\n\n start\n : Don't return kind names before this in alphabetical order.\n\n end\n : Don't return kind names after this in alphabetical order.\n\nget_properties_of_kind(kind, start=None,\nend=None):\n: Returns a list of property names for the given \u003cvar translate=\"no\"\u003ekind\u003c/var\u003e name\n in the current namespace.\n\n **Arguments**\n\n kind\n : Which kind's properties to list.\n\n start\n : Don't return property names before this in alphabetical order.\n\n end\n : Don't return property names after this in alphabetical order.\n\n\nget_representations_of_kind(kind, start=None,\nend=None)\n: Returns a `dict` mapping property names for the given kind name\n to lists of representation names such as 'STRING', 'BOOLEAN' or 'INT64'.\n Only looks in the current namespace.\n For a complete list of these types, see\n [Representation Types](#representations)\n\n: Returns a list of property names for the given \u003cvar translate=\"no\"\u003ekind\u003c/var\u003e name.\n\n **Arguments**\n\n kind\n : Which kind's properties to list.\n\n start\n : Don't return property names before this in alphabetical order.\n\n end\n : Don't return property names after this in alphabetical order.\n\nRepresentation Types\n--------------------"]]
