Tkinter GUI address book management system

tkinter GUI Version address book management system

The experimental requirements

To design a GUI Address book of version , Connect data.db database （ The database is QQ Group file ）, Read out the address book records in the database , Place a table on the window to display the address book information , Use Treeview Component implementation , Then display the name, etc. in the form 6 A field , And add （ You can't add someone's information repeatedly ） And delete records . Improving the function requires error handling and information prompt when adding records . The interface is as follows ：
