Python 如何在为类变量赋值时减少样板代码

是否有任何方法可以简化此代码，因为每次输入实例名来访问类变量都很烦人。我基本上是在构建Kotlin后台，我们使用

和
来访问类的属性

科特林例如：

val notification  = Notification()

with(notification){
created_at = datetime.datetime.now()
recipient_id = recipient
//etc

}

通知.py

class Notification(CustomerBase, Base):
    __tablename__ = "notification"
    created_at = Column(DateTime, nullable=True, default=datetime.datetime.now())
    recipient_id = Column(Integer, ForeignKey("users.id"), nullable=True)
    sender_id = Column(Integer, ForeignKey("users.id"), nullable=True)
    data = Column(JSONB, nullable=True)
    message = Column(String, nullable=True)
    type = Column(String, nullable=True)
    activity_id = Column(Integer, nullable=True)
    is_read = Column(BOOLEAN, nullable=True, default=False)
    sender_info = relationship("User", foreign_keys=[sender_id])
    recipient_info = relationship("User", foreign_keys=[recipient_id])
    entity_id = Column(Integer, nullable=True)
    entity_name = Column(String, nullable=True)

将通知保存到会话

                notification = Notification()
                notification.created_at = datetime.datetime.now()
                notification.recipient_id = recipient
                notification.sender_id = activity.created_by
                notification.message = add_people_msg(user, added_user, activity)
                notification.type = NotificationTypes.PEOPLE.value
                notification.customer_id = activity.customer_id
                notification.entity_id = activity.id
                notification.customer_id = activity.customer_id
                notification.activity_id = activity.id
                notification.data = activity_data

                self.session.add(notification)

这是更多的代码行，但较少的重复

也许会有帮助。
