Python utils.walk_json_dict函数代码示例

def mk_readable_msg(msg):

  Produces a unit test case from a parsed SBP message. The case

  Parameters
  ----------
  msg : Subclass of :class: `SBP`.
    Parsed SBP message.
  keys : list
    List of keys to remove from the rendered

  Returns
  ----------
  A dict formatted for a unit test case.
