(The definition of `y` does not generate a linter message.)\r\n\r\n## Steps to reproduce:\r\n1. Create python 3.6 file with above code.\r\n2. Python: Run Linting\r\n\r\n## Logs\r\n\r\nNone\r\n\r\nOutput from `Console` under the `Developer Tools` panel (toggle Developer Tools on under `Help`)\r\n\r\nNone\n\n","author":{"url":"https://github.com/brettcannon","@type":"Person","name":"brettcannon"},"datePublished":"2018-12-10T20:16:33.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/476/python-language-server/issues/476"}
