The project is a Contact Management System developed using Python and the Tkinter library for the GUI (Graphical User Interface). The application allows users to manage a list of contacts by adding, editing, updating, and deleting entries stored in an SQLite database. It provides a simple interface with textboxes for input and a table (Treeview) for displaying the list of contacts.
Contact Management System in Python with source code
1. Database Setup:
- A SQLite database (`contacts.db`) is created with a table named `contacts`.
- The table includes fields: `id` (primary key, auto-incremented), `name`, `phone`, and `email`.
2. Adding Contacts:
- User enters contact details (name, phone, email) into textboxes.
- Upon clicking the "Add Contact" button, the details are saved into the database.
- The contact list is refreshed to display the new entry.
3. Editing Contacts:
- User selects a contact from the list (Treeview).
- Upon clicking the "Edit Contact" button, the selected contact's details are loaded into the textboxes.
- The user can modify the details in the textboxes.
4. Updating Contacts:
- After editing, the user clicks the "Update Contact" button.
- The modified details are updated in the database based on the contact's ID.
- The contact list is refreshed to display the updated information.
5. Deleting Contacts:
- User selects a contact from the list.
- Upon clicking the "Delete Contact" button, the selected contact is removed from the database.
- The contact list is refreshed to exclude the deleted entry.
6. Listing Contacts:
- The application displays the contact list in a Treeview widget.
- It fetches all entries from the database and displays them in a tabular format with columns: ID, Name, Phone, and Email.
Development Language and Technologies
- Programming Language: Python
- GUI Framework: Tkinter (Python's standard GUI toolkit)
- Database: SQLite (lightweight database engine included with Python)
- Libraries Used:
- `tkinter`: For creating the GUI, handling user inputs, and displaying the contact list.
- `sqlite3`: For database operations such as creating tables, inserting, updating, and deleting records.
- `ttk`: A submodule of Tkinter used for the Treeview widget, which displays the contacts in a table format.
Development Steps
1. Set Up the Environment:
- Ensure Python is installed.
- No additional installations are needed for Tkinter and SQLite as they are included in the standard Python library.
2. Create the Database:
- Write the code to initialize the SQLite database and create the necessary table.
3. Develop the GUI:
- Use Tkinter to create the main window, forms for input (textboxes), buttons for actions, and a Treeview for displaying contacts.
4. Implement Functionality:
- Write functions for adding, updating, deleting, and listing contacts.
- Connect these functions to the respective buttons in the GUI.
5. Testing and Debugging:
- Test each feature thoroughly to ensure the application handles adding, updating, editing, and deleting contacts as expected.
- Debug any issues with button functionality, data handling, or database connections.
6. Deploy and Use:
- The application can be deployed as a standalone Python script.
- Users can run the script to manage their contacts locally.
This workflow and technology stack provide a straightforward and efficient way to manage contacts using Python and Tkinter, with SQLite serving as the backend database.
