使用Python实现将excel表中的数据调入数据库sqlite3中，并实现数据库的的增删改查

具体实现功能如下

1. 自行创建一个“Address.xlsx”班级通讯录表格文件，表格中包含学号、姓名、电话、邮箱、地址等信息，并在表格中输入至少5行数据记录。编写Python程序，完成将Excel表格文件的通讯录信息导入到sqlite3数据库中。

2. 编写一个AddressBook类，类中包含selectInfo,insertInfo,deleteInfo,
   updateInfo等四个函数用于实现对数据库中通讯录的增删查改操作。

3.实例化AddressBook类的对象，使用本人信息测试完成对通讯录的数据处理操作。

AddressBook类

    四个函数用于实现对数据库中通讯录的增删查改操作"""
