HW$2$: Shortbread Calculator

$20$ Points

Shortbread. Who doesn$$t love it$,$ and with just three ingredients, who couldn$$t make it$?$ And with

your help, this dense, buttery treat is about to get even easier.

Your Task

Code a Python Shortbread Calculator that will allow a user to $1)$ customize a recipe size and $2)$

view nutritional information. A simple shortbread cookie recipe uses $1$C butter, $(1)/(2)$C sugar, and

$2$C flour to make $16$ cookies. Your calculator will display custom ingredient amounts for any

number of cookies the user enters. For example, the following user is wanting to make a half recipe

of $8$ cookies $($of which they will eat $4).$ User input is circled to differentiate it from output:

A recipe of $4$ cookies $($and eating $2)$ will produce the following output:

Use the following data in your calculations:

Standard Shortbread Recipe $16$ Cookies

Butter $1$ Cup

Sugar $(1)/(2)$ Cup

Flour $2$ Cups

Nutritional Data $1$ Cookie

Calories $160$

Carbs $18$g

Fat $12$g

You may approach this any way you like, but one way would be to begin your program by

calculating the ingredient portions for ONE cookie $($by dividing each of the original recipe portions

by $16),$ and then multiply those results by the user$$s desired number of cookies. The nutritional

data are already given per $1$ cookie, so that will be just straight multiplication.

Since decimal lengths will vary depending on recipe sizes, I$$ll advise you not to fiddle with

decimal formatting at all this program. We$$ll have plenty of opportunities to use that technique

later.

When you$$re done, submit your $.$py file $($or zipped $.$py file as a $.$zip$)$ through Canvas.
