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 = titleself.author = authordef 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 = narratordef 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()
