Description

inspect.__doc__

Produce an inspection object for the given target.

    The returned value in some cases may be the
    same object as the one given, such as if a
    :class:`_orm.Mapper` object is passed.   In other
    cases, it will be an instance of the registered
    inspection type for the given object, such as
    if an :class:`_engine.Engine` is passed, an
    :class:`_reflection.Inspector` object is returned.

    :param subject: the subject to be inspected.
    :param raiseerr: When ``True``, if the given subject
     does not
     correspond to a known SQLAlchemy inspected type,
     :class:`sqlalchemy.exc.NoInspectionAvailable`
     is raised.  If ``False``, ``None`` is returned.
