Source Code

import tkinter
import tkinter as ttk
from tkinter import *

root = tkinter.Tk()
root.title("Tk dropdown example")

# Add a grid
mainframe = tkinter.Frame(root)
mainframe.grid(column=0, row=0, sticky=(tkinter.N, tkinter.W, tkinter.E, tkinter.S))
mainframe.columnconfigure(0, weight = 1)
mainframe.rowconfigure(0, weight = 1)
mainframe.pack(pady = 100, padx = 100)

# Create a Tkinter variable
tkvar = tkinter.StringVar(root)

# Dictionary with options
choices = { 'PYTHON','C','C++','PHP','JAVA'}
tkvar.set('PYTHON') # set the default option

popupMenu = tkinter.OptionMenu(mainframe, tkvar, *choices)
tkinter.Label(mainframe, text="Choose Programming Language").grid(row = 1, column = 1)
popupMenu.grid(row = 2, column =1)

# on change dropdown value
def change_dropdown(*args):
    print( tkvar.get() )

# link function to change dropdown
tkvar.trace('w', change_dropdown)

root.mainloop()

Frequently Asked Questions

How does this Python project work?

Built with Python 3.10+ and either Tkinter (desktop GUI), Django (web), or Flask (lightweight web). Standard structure: main.py launches the app, modules organized by feature, SQLite/MySQL for persistence.

What Python version and libraries does this project require?

Most projects in this batch use Python 3.10, 3.11, or 3.12 (avoid 3.13 until library wheels catch up). Standard libs: tkinter (built-in), sqlite3 (built-in). External: pip install pillow opencv-python pygame mysql-connector-python reportlab requests beautifulsoup4. Check the requirements.txt file (if included) for exact versions.

How do I set up the database for this Python project?

For SQLite (most common, no setup needed): the .db file auto-creates on first run. For MySQL: install MySQL Server + MySQL Workbench, create an empty database, import the included .sql file, edit the connection string in db.py (or db_connect.py) with your host, user, password, database name.

Can I use this Python project for a BSIT capstone or thesis?

Yes. Python is rising fast in Philippine BSIT panels. Extend it: add user roles via auth module, dashboards (matplotlib charts), PDF reports (reportlab), email notifications (smtplib), real domain extension (analytics, audit log, multi-branch support). Pair with Chapter 1-5 documentation matching your panel’s rubric.

Why am I getting ‘ModuleNotFoundError’ or ‘No module named X’?

Three common Python issues: (1) Module not installed: pip install (use pip3 on macOS/Linux). (2) Wrong virtualenv: activate the project’s venv before running (python -m venv venv then venv\Scripts\activate on Windows or source venv/bin/activate on Linux/macOS). (3) Python 2 vs Python 3 mismatch: ensure you run python3 main.py not python main.py if both are installed.

Where can I find more Python projects with source code?

Browse the Python Projects hub for the full library. For computer vision specifically see OpenCV Projects (46 vision systems). For ML / AI capstones see Machine Learning Projects. For BSIT capstone idea lists see 150 Best Capstone Project Ideas.
