The behavior is explained in the [Python FAQ](https://docs.python.org/3/faq/programming.html#why-am-i-getting-an-unboundlocalerror-when-the-variable-has-a-value), and the solution is to declare `basestring` as global explicitly.\r\n\r\n","author":{"url":"https://github.com/imankulov","@type":"Person","name":"imankulov"},"datePublished":"2020-06-10T07:58:12.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/432/hyper/issues/432"}
