  attribute name and type.
  
  Exampels:
      >>> from towhee.datacollection.entity import Entity
      >>> e = Entity(a=1, b=2)
      >>> e
      <Entity dict_keys(['a', 'b'])>
      >>> e.a
      1
      >>> e.b
      2
docstr: Return the str representation of an Entity.
  
  Returns (`str`):
      The string representation of the entity.
  
  Examples:
      >>> from towhee.datacollection.entity import Entity
      >>> e = Entity(a = 1, b = 2)
      >>> str(e)
      "{'a': 1, 'b': 2}"
