The :class:`.Row` object represents a row of a database result. It is typically associated in the 1.x series of SQLAlchemy with the :class:`_engine.CursorResult` object, however is also used by the ORM for tuple-like results as of SQLAlchemy 1.4. The :class:`.Row` object seeks to act as much like a Python named tuple as possible. For mapping (i.e. dictionary) behavior on a row, such as testing for containment of keys, refer to the :attr:`.Row._mapping` attribute. .. seealso:: :ref:`tutorial_selecting_data` - includes examples of selecting rows from SELECT statements. .. versionchanged:: 1.4 Renamed ``RowProxy`` to :class:`.Row`. :class:`.Row` is no longer a "proxy" object in that it contains the final form of data within it, and now acts mostly like a named tuple. Mapping-like functionality is moved to the :attr:`.Row._mapping` attribute.
