Wrong:

    >>> res = session.query(Student.name, Student.year).all()
    >>> type(res)
    <class 'list'>
    >>> type(res[0])
    <class 'sqlalchemy.util._collections.result'>
    >>> type(res[0].name)
    <class 'str'>
    >>> type(res[0][0])
    <class 'str'>
    >>> res[0].name == res[0][0]
    True
