BMI Calculator That Returns Value and Category

Easy ⏱ 8 min 73% acceptance ★★★★☆ 4.3

Write a function bmi(weight_kg, height_m) that computes Body Mass Index as weight_kg / height_m ** 2, rounded to 1 decimal place, and returns a tuple (bmi_value, category) where category is "Underweight" if bmi < 18.5, "Normal" if 18.5 <= bmi < 25, "Overweight" if 25 <= bmi < 30, and "Obese" otherwise.
