A simple Python Expense Tracker built with Tkinter (GUI) and SQLite (database).
This project was developed as part of Week 5 in my AI learning journey.
It allows users to:
- Add expenses with a description, amount, and custom date
- View expenses for Today, All, or a specific date
- Delete expenses from the list
- Automatically calculate and display the total spent
- Use scrollable lists for easy navigation of records
✅ Add expenses with description and amount
✅ Store data permanently using SQLite
✅ Filter expenses by Today, All, or a Custom Date
✅ Auto-numbering for expense entries
✅ Display total expenses dynamically
✅ Scrollbars for handling long records
✅ Clean Tkinter-based GUI
- Language: Python 3.x
- GUI: Tkinter
- Database: SQLite3
This project was a bit challenging because of:
- Debugging the date filter, where past expenses were showing up in the wrong date view
- Fixing the entry numbering system, so every date view starts from
1instead of continuing - Handling scrollbars for long expense lists
Working through these bugs gave me hands-on practice in debugging and improving my Python + Tkinter skills.
This will be my last Python project before moving into Data Science & AI development, which includes:
- Linear Algebra
- Statistics for AI
- Vectors & Matrices
- NumPy & Pandas
- Matplotlib & Data Visualization
This project strengthened my understanding of:
- Working with SQLite databases in Python
- Building interactive GUIs with Tkinter
- Implementing filters and dynamic lists
- Debugging and testing projects for real-world use
