Code Explanations
1. Importing Tkinter Module
Code:
from tkinter import *
Explanation:
In the code given below, which is for the function for importing tkinter. Tkinter is the standard GUI library for Python. Python when combined with Tkinter provides a fast and easy way to create GUI applications.
2. This module is for the BMI calculator
Code:
def BodyMassIndex_Calculator():
BMI_Height = float(variable2.get())
BMI_Weight = float(variable1.get())
BodyMassIndex = str('%.2f' % (BMI_Weight / (BMI_Height * BMI_Height)))
lbl_res_bmi.config(text=BodyMassIndex)Explanation:
In the code given below, which is for the function for BMI calculator.
3. This module is for the design for main window
Code:
Tops = Frame(application, width=1350, height=50, bd=8, relief="raise")
Tops.pack(side=TOP)
frame1 = Frame(application, width=600, height=600, bd=8, relief="raise")
frame1.pack(side=LEFT)
frame2 = Frame(application, width=300, height=700, bd=8, relief="raise")
frame2.pack(side=RIGHT)
frame1A = Frame(frame1, width=600, height=200, bd=20, relief="raise")
frame1A.pack(side=TOP)
frame1B = Frame(frame1, width=600, height=600, bd=20, relief='raise')
frame1B.pack(side=TOP)
lbl_T1 = Label(Tops, text=" BODY MASS INDEX ", padx=16, pady=16, bd=16, fg='#000000',
font=("arial", 54, 'bold'), bg="navajo white", relief='raise', width=32, height=1)
lbl_T1.pack()
lbl_w = Label(frame1A, text="Select Weight in Kilograms", font=('arial', 20, 'bold'), bd=20).grid(row=0, column=0)
b_w = Scale(frame1A, variable=variable1, from_=1, to=500, length=880, tickinterval=30, orient=HORIZONTAL)
b_w.grid(row=1, column=0)
lbl_h = Label(frame1B, text="Enter Height in Meters Square", font=('arial', 20, 'bold'), bd=20).grid(row=0, column=0)
t_h = Entry(frame1B, textvariable=variable2, font=('arial', 16, 'bold'), bd=16, width=22, justify='center')
t_h.grid(row=1, column=0)
lbl_res_bmi = Label(frame1B, padx=16, pady=16, bd=16, fg='#000000', font=('arial', 30, 'bold'), bg='navajo white',
relief='sunk', width=34, height=1)
lbl_res_bmi.grid(row=2, column=0)Explanation:
In the code given below, which is for the function for the design of BMI screen windows. You can see the frame, and the label use in the system.
4. This module is the design for BMI table
Code:
lbl_table_bmi = Label(frame2, font=("arial", 20, 'bold'), text='BMI Table').grid(row=0, column=0)
bmi_tab_text_lbl = Text(frame2, height=12, width=38, bd=16, font=("arial", 12, 'bold'))
bmi_tab_text_lbl.grid(row=1, column=0)
bmi_tab_text_lbl.insert(END, 'Meaning \t\t' + "BMI \n\n")
bmi_tab_text_lbl.insert(END, 'Normal weight \t\t' + "19-24 \n\n")
bmi_tab_text_lbl.insert(END, 'Overwight \t\t' + "25-29,9 \n\n")
bmi_tab_text_lbl.insert(END, 'Obesity level I \t\t' + "30-34, 9 \n\n")
bmi_tab_text_lbl.insert(END, 'Obesity level II \t\t' + "35-39, 9\n\n")
bmi_tab_text_lbl.insert(END, 'Obesity level III \t\t' + ">= 40\n\n")Explanation:
In the code given below, which is for the function for the design of BMI table.

Frequently Asked Questions
How does this Python calculator project work?
Built with Tkinter Frame + Entry widget + Button grid. Each digit/operator button appends to display. = button uses eval() (simple) or proper expression parser (safer). Foundation for any GUI Python beginner project.
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
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.
