python图书管理系统

好的，Python 图书管理系统可以分为以下几个模块：

1. 登录模块：实现管理员的登录功能，需要输入用户名和密码。

2. 图书管理模块：包括添加图书、删除图书、修改图书信息、查询图书信息等功能。

3. 读者管理模块：包括添加读者、删除读者、修改读者信息、查询读者信息等功能。

4. 借还书管理模块：包括借书、还书、续借等功能。

5. 统计模块：包括查看图书借阅排行榜、查看借阅记录等功能。

下面是一个简单的 Python 图书管理系统代码示例：

class Book:
    def __init__(self, book_id, book_name, author, publisher, publish_date, price, total_num, remain_num):
        self.book_id = book_id  # 图书ID
        self.book_name = book_name  # 图书名称
        self.author = author  # 作者
        self.publisher = publisher  # 出版社
        self.publish_date = publish_date  # 出版日期
        self.price = price  # 价格
        self.total_num = total_num  # 总数量
        self.remain_num = remain_num  # 剩余数量

class Reader:
    def __init__(self, reader_id, reader_name, reader_type):
        self.reader_id = reader_id  # 读者ID
        self.reader_name = reader_name  # 读者姓名
        self.reader_type = reader_type  # 读者类型，如学生、教师等

class BorrowRecord:

以上是一个简单的 Python 图书管理系统的代码示例，可以根据实际需求进行修改和完善。
