Python 图书馆志愿者值班管理系统：换班、调班、请假审批

作为图书馆管理者，您需要管理志愿者的值班情况，并处理换班、调班、请假等请求。本文将提供一个使用 Python 开发的简单值班管理系统，帮助您高效管理志愿者值班。

系统功能:

值班表管理: 支持添加、删除、修改值班信息，并展示当前的值班表。
换班请求: 志愿者可以请求与其他志愿者交换班次，管理员审核后进行操作。
调班请求: 志愿者可以请求调整自身班次，管理员审核后进行操作。
请假申请: 志愿者可以提交请假申请，管理员审核后进行操作。
管理员审批: 管理员可以审核所有换班、调班、请假请求，并进行批准或拒绝操作。

使用方法:

创建 volunteers.csv 和 shifts.csv 文件，分别存储志愿者信息和值班信息。
运行 Python 代码，选择相应功能进行操作。

注意: 代码中省略了管理员审核部分，您需要根据实际需求添加管理员身份验证和审核流程。

代码说明:

代码使用了面向对象的编程方式，定义了 Volunteer、Shift 和 LibrarySchedule 类来表示志愿者、班次和值班表。
代码使用了 CSV 文件来存储和读取数据，方便管理和维护。
代码提供了清晰的接口和注释，便于理解和修改。

扩展功能:

添加管理员用户管理功能。
添加邮件或短信通知功能，提醒志愿者值班或审批结果。
使用数据库来存储数据，提高系统性能和安全性。

希望本代码示例能帮助您快速构建图书馆志愿者值班管理系统。您可以在此基础上进一步完善功能，满足您的实际需求。
