图书类Book, 包括书名、出版社名称、作者姓名、图书定价等数据成员。编程序完成Book类的设 计，从键盘读入10本图书的各项数据，并、将这10本图书的相关数据写入磁盘文件book.dat 中，然后从 book.dat中读出图书数据，计算所有图书的总价，显示每本图书的详细信息，每本图书的信息显示在一行上

好的，我已经明白了你的问题。下面是 Book 类的设计，以及实现你所需要的功能的示例代码：

import pickle

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

    def __str__(self):
        return f"{self.title} ({self.author}), published by {self.publisher}, priced at {self.price}"

# 从键盘读入10本图书的各项数据
books = []
for i in range(10):
    title = input(f"Please enter the title of book {i+1}: ")
    publisher = input(f"Please enter the publisher of book {i+1}: ")
    author = input(f"Please enter the author of book {i+1}: ")
    price = float(input(f"Please enter the price of book {i+1}: "))
    books.append(Book(title, publisher, author, price))

# 将这10本图书的相关数据写入磁盘文件book.dat中
with open("book.dat", "wb") as f:
    pickle.dump(books, f)

# 从book.dat中读出图书数据
with open("book.dat", "rb") as f:
    books = pickle.load(f)

# 计算所有图书的总价，显示每本图书的详细信息，每本图书的信息显示在一行上
total_price = 0
for book in books:
    print(book)
    total_price += book.price
print(f"The total price of all books is {total_price}.")

这个程序使用 pickle 模块来实现序列化和反序列化，将 Book 对象写入和读出磁盘文件。你可以将这段代码复制到你的 Python 环境中运行，看看效果如何。
