如何使用sqlalchemy查询数组中的特定列？

from sqlalchemy import create_engine, Column, Integer, String, ARRAY
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.orm import sessionmaker

engine = create_engine('数据库连接字符串')
Session = sessionmaker(bind=engine)
session = Session()

Base = declarative_base()

class MyModel(Base):
    __tablename__ = 'my_table'
    id = Column(Integer, primary_key=True)
    data = Column(ARRAY(String))

result = session.query(MyModel.data[0], MyModel.data[2]).all()

for row in result:
    print(row)
