Calculate BMI

Write function bmi that calculates body mass index (bmi = weight / height ^ 2).

if bmi <= 18.5 return "Underweight"

if bmi <= 25.0 return "Normal"

if bmi <= 30.0 return "Overweight"

if bmi > 30 return "Obese"

---

Given Code

def bmi(weight, height):
    pass

---

Solution 1

def bmi(weight, height):
    bmi = weight / height ** 2
    if bmi <= 18.5 : return "Underweight"
    elif bmi <= 25 : return "Normal"
    elif bmi <= 30 : return "Overweight"
    else: return "Obese"

---

Solution 2

def bmi(weight, height):
    b = weight / height ** 2
    return ['Underweight', 'Normal', 'Overweight', 'Obese'][(b > 30) + (b > 25) + (b > 18.5)]
