如何打印sqlalchemy查询中的所有列？

from sqlalchemy import create_engine, MetaData, Table
from sqlalchemy.orm import sessionmaker

engine = create_engine('数据库连接字符串')

Session = sessionmaker(bind=engine)
session = Session()

metadata = MetaData(bind=engine)
table = Table('表名', metadata, autoload=True)

result = session.query(table).all()
for row in result:
    print(row)
