weight = float(input('Enter your weight(in kilograms): '))

height = float(input('Enter your height(in metres): '))

After the values are been entered, it calculates the BMI value using the values the user provided and displays the BMI value.

bmi = weight / (height ** 2)

print('Your body mass index is ', bmi, 'kg/m^2')

The program also tells the you about which weight classification your BMI value fall under, using the standard BMI classification chart.

if bmi < 18.5 :

print('This is considered underweight')

elif 18.5 <= bmi < 25:
