Given the code for a class definition, I am trying to extract all attributes and their comments ("" empty string if no comments).

class Player(Schema):
    score = fields.Float()
    """
    Total points from killing zombies and finding treasures
    """

    name = fields.String()
    age = fields.Int()

    backpack = fields.Nested(
        PlayerBackpackInventoryItem,
        missing=[PlayerBackpackInventoryItem.from_name("knife")],
    )
    """
    Collection of items that a player can store in their backpack
    """

In the above example, we expected the parsed result to be:

[
  ("score", "Total points from killing zombies and finding treasures"),
  ("name", ""),
  ("age", ""),
  ("backpack", "Collection of items that a player can store in their backpack")
]

In my attempt below, it is failing to extract the comments properly, giving an output:

[
  ('score', 'Total points from killing zombies and finding treasures'), 
  ('name', ''), 
  ('age', ''), 
  ('backpack', '')
]

How can the regex expression (or even the entire parsing logic) be fixed to handle the situations present in the example class code?

Thanks
