Expense Tracker

Overview

The Expense Tracker is a Python-based desktop application designed to help users manage and monitor their daily expenses. The application provides a clean and intuitive interface using the tkinter library and supports basic CRUD operations (Create, Read, Update, Delete). It also includes features like expense categorization, summaries, and data persistence using an SQLite database.

This project demonstrates Object-Oriented Programming (OOP) principles, GUI development, and database integration, making it a comprehensive example of Python application development.

Installation

Follow these steps to set up and run the Expense Tracker system:

Prerequisites

1. Make sure Python 3.6 or later is installed on your computer. You can download it from the official Python website: https://www.python.org/downloads/.

2. Confirm Python is installed by checking its version. This ensures compatibility.

Clone the Repository

1. Clone the repository to your local machine:

git clone https://github.com/Hanjishi/Expense_Tracker.git

2. Navigate into the project directory:

cd Expense_Tracker

Run the Application

1. Start the application directly by running the following command:

python app.py or python3 app.py

2. The Expense Tracker UI will launch, and you can begin tracking your expenses.

Notes No additional installations are needed since the system only uses built-in Python libraries (tkinter and sqlite3). Make sure your Python installation includes tkinter, as it is required for the GUI.
