如何在SQLAlchemy中访问“枚举”列数据类型？

pip install SQLAlchemy

from sqlalchemy import create_engine, Column, Enum, Integer, String
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)
    enum_column = Column(Enum('值1', '值2', '值3'))

results = session.query(MyModel).all()
for result in results:
    print(result.enum_column)
