Therefore, if the result of the `run_process` method is not a string,we might expect it to fail, and indeed it does.\"\r\n\r\nI cannot understand why the code just prior to this sentence would fail, since we wrap the `result` variable with `str()`. Can you confirm that I am correct in my assessment that the code would _not_ fail? Or am I misunderstanding the description?\r\n\r\nIt seems that the `Process` class in example ch08/ut_design_1.py _would not_ fail, but the `Process` class in example ch08/ut_design_2.py _would_ fail, hence my confusion.\r\n\r\nKind regards,\r\n\r\nDawie Diamond ","author":{"url":"https://github.com/dawiediamondinvoke","@type":"Person","name":"dawiediamondinvoke"},"datePublished":"2021-04-05T12:29:39.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/63/Clean-code-in-Python/issues/63"}
