Introducing our Expense Tracker – a Python app simplifying personal finance. With a user-friendly interface and modularity, effortlessly manage expenses and promote financial well-being.

Expense Tracker

Expense Tracker is a desktop application that aligns with SDG#1, SDG#8 and SDG#12 designed to help you manage your expenses effectively. This README provides detailed instructions and insights into the project.

Overview

The Expense Tracker allows users to record and track their spending by category. The application provides a user-friendly interface for adding, viewing, searching, and managing expense records. Additionally, it offers graphical representation of expenses by category through interactive graphs.

Features

Record Management:

• Add new records to the expense table.

• Delete records in the expense table.

• View all recorded expenses.

• Search for specific records by title, price, or category.

Graphical Representation:

• Visualize expenses through interactive graphs.

• Categories are represented for a clear overview of spending patterns.

Error Handling:

• The application provides error messages for blank fields, incorrect text lengths, and invalid inputs.

Technologies Used

Python: The primary programming language.

Pandas: Used for data manipulation and analysis.

Plotly: Enables the creation of interactive and visually appealing graphs.

SQLite3: The database management system for storing expense records.

Tkinter and ttkbootstrap: Provide the graphical user interface for the desktop application.

Implementation

DRY Method (Don't Repeat Yourself):

In our code, We embrace the DRY principle to avoid code duplication. Take, for example, the create_treeview function in main.py. It's designed to instantiate and configure a Treeview widget, consolidating the widget creation logic in one place for efficient reuse. This not only streamlines the code but also enhances maintainability.

OOP Principles (Object-Oriented Programming):

We incorporated object-oriented programming (OOP) principles by introducing the Budget class to manage interactions with the database. Creating an instance, such as budget = Budget(), enables the use of dot notation to access methods and properties seamlessly across the codebase.

Simplicity and Robustness:

We prioritize simplicity for clarity and maintainability, ensuring each code block serves a specific purpose. While basic error handling is in place using messagebox.showwarning, there's room for further enhancements to fortify the code's robustness. The aim is a balanced approach, making the application both easy to understand and resilient.
