python - 如何创建一个具有大量属性而不重复代码的类？

Question

我有以下类来表示新闻提醒

class Incident:
    news_id: Optional[str] = None
    created_at: str
    service: str
    status: str
    title: str
    content: str
     category: Optional[str] = None
    news_url: Optional[str] = None
    updated_at: Optional[str] = None
    published_at: Optional[str] = None
    city: Optional[str] = None
    state: Optional[str] = None
    ....
     def __init__(self,
                 status: str, service: str, created_at: str, title: str, content: str, news_id: Optional[str] = None,
                 category: Optional[str] = None, news_url: Optional[str] = None, updated_at: Optional[str] = None,
                 published_at: Optional[str] = None, city: Optional[str] = None, state: Optional[str] = None,
                 country: Optional[str] = None, address: Optional[str] = None, region: Optional[str] = None,
                 latitude: Optional[float] = None, longitude: Optional[float] = None,
                 images: Optional[List[Dict[str, str]]] = None):
        self.news_id = news_id
        self.status = status
        self.category = category
        self.service = service
        self.title = title
        self.content = content
        self.news_url = news_url
        self.created_at = created_at
        self.updated_at = updated_at
        self.published_at = published_at
        self.city = city
        self.state = state
        self.country = country
        self.address = address
        self.region = region
        self.latitude = latitude
        self.longitude = longitude
        self.images = images

我觉得全类看起来都很丑。属性列出了三次。

我是Python新手，想知道有什么方法可以更清晰地组织它吗？也许与数据类一起。

你可以做类似的事情

class Test:
    def __init__(self, **kwargs):
        for key, value in kwargs.items():
            setattr(self, key, value)


test = Test(a=1, b=2)
print(test.a)
print(test.b)

但是，我会重新思考整个类(class)结构。类不仅仅是字典，属性也应该在某个地方使用。如果不是，它们只是一个数据结构。如果是，您可能应该将这些参数的子集分组到其他类中。
