Body Mass Index (BMI) calculator

Body Mass Index(BMI) is a simple calculation using a person’s height and weight.

The formula is BMI = kg/m2 where kg is a person’s weight in kilograms and m2 is their height in meters squared. A BMI of 25.0 or more is overweight, while the healthy range is 18.5 to 24.9.




The user needs to fill in some information like age, gender, height & weight. Out of this information height & weight is used to calculate the BMI. Then the BMI passes through conditions.

Each condition has a remark (underweight, Normal, overweight, etc). The result is displayed using a message box as shown above.



The above code was used to come up with BMi ranges .

BMI Categories:

  • Underweight = <18.5

  • Normal weight = 18.5–24.9

  • Overweight = 25–29.9

  • Obesity = BMI of 30 or greater

Below is how the code was formulated

#Import tkinter,an interface that will be used to calculate BMI

from tkinter import*from tkinter import messagebox

# Defining parameters
def reset_entry():age_tf.delete(0,'end')height_tf.delete(0,'end')weight_tf.delete(0,'end')
def calculate_bmi():kg = int(weight_tf.get())m = int(height_tf.get())/100bmi = kg/(m*m)bmi = round(bmi, 1)bmi_index(bmi)
def bmi_index(bmi):if bmi < 18.5:messagebox.showinfo('bmi-pythonguides', f'BMI = {bmi} is Underweight')
 elif (bmi > 18.5) and (bmi < 24.9):messagebox.showinfo('bmi-pythonguides', f'BMI = {bmi} is Normal')
 elif (bmi > 24.9) and (bmi < 29.9):messagebox.showinfo('bmi-pythonguides', f'BMI = {bmi} is Overweight')
 elif (bmi > 29.9):messagebox.showinfo('bmi-pythonguides', f'BMI = {bmi} is Obesity')
 else:messagebox.showerror('bmi-pythonguides', 'something went wrong!')

Again, using is the coping your code in a code snippet is better than using images.

Where in your code did you implement displaying the result as you described?
