如何在SQLAlchemy查询中获取列名？

from sqlalchemy import create_engine

engine = create_engine('sqlite:///your_database.db')

from sqlalchemy import Column, Integer, String
from sqlalchemy.ext.declarative import declarative_base

Base = declarative_base()

class User(Base):
    __tablename__ = 'users'
    
    id = Column(Integer, primary_key=True)
    name = Column(String)
    age = Column(Integer)

from sqlalchemy.orm import sessionmaker

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

query = session.query(User)
result = query.first()

column_names = result.__table__.columns.keys()
print(column_names)
