python面向对象编程题——有声书系统

设计一个图书管理系统,

基类为类Book,要求有书名和作者属性，

由Book类派生子类AudioBook(有声书，需要具有演说者属性)，

对于Book和AudioBook进行合理的属性及行为的抽象，

编写图书管理类用于管理图书以及有声图书

class Book:
    def __init__(self, title, author):
        self.title = title
        self.author = author

    def display_info(self):
        print(f"书名: {self.title}, 作者: {self.author}")


class AudioBook(Book):
    def __init__(self, title, author, narrator):
        super().__init__(title, author)  # 调用父类的构造器
        self.narrator = narrator

    def display_info(self):
        # 重写父类的方法以包含演说者信息
        print(f"书名: {self.title}, 作者: {self.author}, 演说者: {self.narrator}")


class Library:
    def __init__(self):
        self.books = []  # 存储所有图书的列表

    def add_book(self, book):
        self.books.append(book)

    def display_all_books(self):
        for book in self.books:
            book.display_info()

        # 示例使用


if __name__ == "__main__":
    lib = Library()
    lib.add_book(Book("Python编程", "张三"))
    lib.add_book(AudioBook("Python编程有声版", "李四", "王五"))
    lib.display_all_books()
