The Body Mass Index (BMI) is used to determine whether an adult is overweight or underweight for his or her height. The formula used to calculate the BMI of an adult is
BMI = weight(in kg)/ (height*height(in meter))
In this program, BMI calculator is to be built using python. To understand concepts, follow this tutorial:
Concepts Covered
if-else, input, f-string, round, data type conversion
Problem Description
Write a program to calculate the BMI of a person on the basis of input taken from a user for the weight (in kg) and height(in m). Once BMI is calculated, the user needs to be indicated based on BMI if the user is underweight, normal, overweight or obese.
BMI Range | BMI Status |
Less than 18.0 | Underweight |
Between 18.0 and 24.9 | Normal weight |
Between 25.0 and 29.9 | Overweight |
30 or More | Obese |
How It Should Work
Approach
Create a variable called weight and store it in weight inputted by the user on prompt. Make sure you convert it into float data type
Create a variable called height and store it in height inputted by the user on prompt. Make sure you convert it into float data type
Calculate BMI using the formula - weight/(height*height) and store it in a variable called BMI
Using if elif and else, compare BMI with different values
print using f-string user's BMI along with the description
