通用卡片设计
类: Card

Card 类是通用卡片的基础类,它有以下属性:

  • title:卡片标题
  • subtitle:卡片副标题
  • description:卡片描述
  • image:卡片图片链接
class Card:
    def __init__(self, title: str, subtitle: str, description: str, image: str):
        self.title = title
        self.subtitle = subtitle
        self.description = description
        self.image = image
子类: TextCard

TextCard 是卡片的一种,它只包含文本信息,不包含图片,其属性只有与 Card 类相同。如下:

class TextCard(Card):
    def __init__(self, title: str, subtitle: str, description: str):
        super().__init__(title, subtitle, description, None)
子类: ImageCard

ImageCard 是卡片的一种,它只包含图片信息,不包含文本,其属性只有与 Card 类相同。如下:

class ImageCard(Card):
    def __init__(self, title: str, subtitle: str, image: str):
        super().__init__(title, subtitle, None, image)
子类: CardGroup

CardGroup 是卡片组的类,它可以包含多个 Card 对象。如下:

class CardGroup:
    def __init__(self, cards: List[Card]):
        self.cards = cards

    def append_card(self, card: Card):
        self.cards.append(card)

    def remove_card(self, card: Card):
        self.cards.remove(card)
使用示例
# 创建 TextCard 对象
text_card = TextCard("Title", "Subtitle", "Description")

# 创建 ImageCard 对象
image_card = ImageCard("Title", "Subtitle", "https://example.com/example.png")

# 创建 CardGroup 并添加卡片对象
card_group = CardGroup([text_card])
card_group.append_card(image_card)
