In this tutorial I am going to create a simple GUI based Python project called BMI Calucator ideal for CBSE Class XI-XII subject Computer science with Python. With out wasting time Let’s see how to create a simple BMI Calculator with Python, In this project I am using tkinter for GUI.
Project Requirement
1. Python 3.X
2. Tkinter Library
Computer science with python project BMI Calculator Full Code

from tkinter import *
from functools import partial
import tkinter as tk
window=tk.Tk()
window.title("BMI Calculator")
def bmi(label_result, ht, wt):
ht = float((ht.get()))
wt = float((wt.get()))
ht=ht/100
bmi=float(wt / (ht*ht))
bmi=round(bmi,1)
conclusion=""
if bmi<18.5:
conclusion="Under Weight"
elif bmi>18.4 and bmi<=24.9:
conclusion="Normal"
elif bmi>24.9 and bmi<=29.9:
conclusion="Over Weight"
else:
conclusion="Obesity"
output= "BMI = "+str(bmi)+"\n" +conclusion
label_result.config(text=output)
return
ht = tk.StringVar()
wt = tk.StringVar()
heightText=Label(window,text="Height (in CM)").grid(row=0, padx=10,pady=10)
height=Entry(window, textvariable = ht ).grid(row=0, column=1, padx=10,pady=10)
weightText=Label(window,text="Weight (in KG)").grid(row=1, padx=10,pady=5)
weight=Entry(window, textvariable = wt ).grid(row=1, column=1, padx=10,pady=5)
labelResult = tk.Label(window)
labelResult.grid(row=4, column=0)
bmi = partial(bmi, labelResult, ht, wt)
btn=Button(window,text="Calculate BMI",command = bmi).grid(row=2, column=1, padx=20,pady=5)
window.geometry("400x300+10+10")
window.mainloop()
