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. :class:`.LegacyRow` - Compatibility interface introduced in SQLAlchemy 1.4. .. 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, but will remain available in SQLAlchemy 1.x series via the :class:`.LegacyRow` class that is used by :class:`_engine.LegacyCursorResult`.

Through the SQLAlchemy 1.x series, the ``__contains__()`` method of :class:`.Row` (or :class:`.LegacyRow` as of SQLAlchemy 1.4) also links to :meth:`.Row.has_key`, in that an expression such as :: "some_col" in row Will return True if the row contains a column named ``"some_col"``, in the way that a Python mapping works. However, it is planned that the 2.0 series of SQLAlchemy will reverse this behavior so that ``__contains__()`` will refer to a value being present in the row, in the way that a Python tuple works. .. seealso:: :ref:`change_4710_core` rrrKs r has_keyLegacyRow.has_keys8||$$S))rzThe :meth:`.LegacyRow.items` method is deprecated and will be removed in a future release.
