Please describe.**\r\nWhen printing out models, we often get extremely verbose strings, such as:\r\n```\r\nCustomEntityUpdate(entity_registry_id=\u003cbenchling_api_client.types.Unset object at\r\n0x10453d2b0\u003e, author_ids=\u003cbenchling_api_client.types.Unset object at 0x10453d2b0\u003e, \r\naliases=\u003cbenchling_api_client.types.Unset object at 0x10453d2b0\u003e, custom_fields=\r\n\u003cbenchling_api_client.types.Unset object at 0x10453d2b0\u003e, \r\nfields=Fields(additional_properties={'Request 1': Field(value='test_plate', \r\ndisplay_value=\u003cbenchling_api_client.types.Unset object at 0x10453d2b0\u003e, is_multi=\r\n\u003cbenchling_api_client.types.Unset object at 0x10453d2b0\u003e, text_value=\r\n\u003cbenchling_api_client.types.Unset object at 0x10453d2b0\u003e, type=\r\n\u003cbenchling_api_client.types.Unset object at 0x10453d2b0\u003e), 'Request 2': \r\nField(value='test_plate', display_value=\u003cbenchling_api_client.types.Unset object at \r\n0x10453d2b0\u003e, is_multi=\u003cbenchling_api_client.types.Unset object at 0x10453d2b0\u003e, \r\ntext_value=\u003cbenchling_api_client.types.Unset object at 0x10453d2b0\u003e, type=\r\n\u003cbenchling_api_client.types.Unset object at 0x10453d2b0\u003e), 'Request 3': \r\nField(value='test_plate', display_value=\u003cbenchling_api_client.types.Unset object at \r\n0x10453d2b0\u003e, is_multi=\u003cbenchling_api_client.types.Unset object at 0x10453d2b0\u003e, \r\ntext_value=\u003cbenchling_api_client.types.Unset object at 0x10453d2b0\u003e, type=\r\n\u003cbenchling_api_client.types.Unset object at 0x10453d2b0\u003e)}), folder_id=\r\n\u003cbenchling_api_client.types.Unset object at 0x10453d2b0\u003e, name=\r\n\u003cbenchling_api_client.types.Unset object at 0x10453d2b0\u003e, schema_id=\r\n\u003cbenchling_api_client.types.Unset object at 0x10453d2b0\u003e)\r\n```\r\n\r\nThis makes debugging much more challenging.\r\n\r\n**Describe the solution you'd like**\r\nIdeally it would print\r\n```\r\nCustomEntityUpdate(fields=Fields(additional_properties={'Request 1': \r\nField(value='test_plate'), 'Request 2': Field(value='test_plate'), 'Request 3': \r\nField(value='test_plate')}))\r\n```\r\n\r\n**Describe alternatives you've considered**\r\nIt would also be an improvement if the repr of `UNSET` itself was shortened. I know @dbanty mentioned a PEP a while back that would allow us to make it a sentinel.\r\n\r\n**Additional context**\r\ncc @GitOnUp\r\n","author":{"url":"https://github.com/forest-benchling","@type":"Person","name":"forest-benchling"},"datePublished":"2021-08-02T14:45:59.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/463/openapi-python-client/issues/463"}
