BMI Calculator

Overview

This Python program calculates and evaluates the Body Mass Index (BMI) of a person based on their weight and height. The BMI is calculated using a mathematical formula, and the program determines if the BMI is within a healthy range, below, or above it.

How It Works

Functions

1. bmi_calculator(w, h):

   • Takes weight (w) in pounds and height (h) in inches as inputs.
   • Returns the calculated BMI.

2. BMI():

   • Prompts the user to enter their weight and height.
   • Calculates the BMI using the bmi_calculator function.
   • Prints the calculated BMI, rounded to two decimal places.
   • Determines if the BMI is within a healthy range, below, or above it, and prints the corresponding message.
