The solution is the declare a `color` variable and assign it any of the `Color` enum values, like so:\r\n\r\n```\r\nfrom enum import Enum\r\nclass Color(Enum):\r\n    RED = 0\r\n    GREEN = 1\r\n    BLUE = 2\r\n\r\ncolor = Color.BLUE\r\n\r\nmatch color:\r\n    case Color.RED:\r\n        print(\"I see red!\")\r\n    case Color.GREEN:\r\n        print(\"Grass is green\")\r\n    case Color.BLUE:\r\n        print(\"I'm feeling the blues :(\")\r\n```","author":{"url":"https://github.com/Aljumaily","@type":"Person","name":"Aljumaily"},"datePublished":"2022-08-14T22:17:18.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/95986/cpython/issues/95986"}
