Gage's Python2 BMI Calculator

bmi.py

"""
This is a BMI calculator written in Python by me (MGage Morgan). The design is minimal atm, but will improve as I get further. 
The BMI formula to use: weight / height^2 x 703

We use a float() wrapped around a raw_input() for 'weight' and 'height'. We do this to prevent Python from thinking we're trying to 
use strings instead of numbers when actually we are not. 
"""
weight = float(raw_input('Enter your weight:\n '))
height = float(raw_input('Enter your height:\n '))

"""
Square splits off a part of the formula to do first (think: PEMDAS). The Order of Operations from math says to do exponents before 
multiplying/dividng. So the 'square' variable holds the value of 'height' being squared so we can conveniently use it later. 
"""
square = height ** 2

"""
'divvy' is the second piece of the problem. This variable holds the 'weight' divided by the pre-calculated 'height squared' to make 
the problem into just two pieces now.
"""
divvy = weight / square

"""
The 'finale' brings it all together. We take the first half ('divvy') and multiply it by 703, as per the CDC's Adult BMI formula. 
"""
finale = divvy * 703

"""
This is more for readability than anything. We round off the number given by 'finale' to the nearest hundredth. This way, it also 
matches the response given on CDC's website. 
"""
rounded_finale = round(finale, 2)

"""
Vóila!! The number can now be printed to the terminal/console as the result. 
"""
print rounded_finale
