I'm not 100% sure exactly what you need, but namedtuple might be what 
you're looking for:

 >>> import collections
 >>> Item = collections.namedtuple('Item', 'id productId quantity 
pageCount files option metadata')
 >>> itm = Item(1, None, 1, 1, 'asdf', {'asdf': 3, 'ads': 55}, None)
 >>> print(itm)
Item(id=1, productId=None, quantity=1, pageCount=1, files='asdf', 
option={'ads': 55, 'asdf': 3}, metadata=None)

See 
https://docs.python.org/3/library/collections.html?highlight=namedtuple#collections.namedtuple
