"""

Part 1:

Per the instructions, the problem prompts the user for the following information:

* Cost per ice cream serving

* Employee labor rate (per hour)

* Shop rental (per month)

* Utilities (per month)

* Advertising (per month)

* Selling price (each)

* ice cream servings sold per month

You program should operate in a loop in which a menu is displayed with the

following options:

------

Expenses:

1. Cost per serving:

2. Labor rate per hour:

3. Shop rental per month:

4. Utilities per month:

5. Advertising budget per month:

Income:

6. Selling price (each):

7. Servings sold per month:

Analysis:

8. Profit/Loss Calculation

9. "What If" analysis with 10% variance

Enter Selection (0 to Exit):

-----

Menu items 1 - 7 should display the current value of the category and allow

the user to change it.

Menu item 8 should display a single value indicating the amount of profit or

loss. It should then, while holding the income fixed, vary the expenses from

- to + 10 percent in 2 percent increments and outputting the values and the

resulting profit or loss in a table. Finally, while holding the expenses

fixed, vary the income parameters from - to + 10 percent in 2 percent increments.

Sample Output:

Enter Selection (0 to Exit): 8

The Ice Cream Shop will have a monthly profit/loss of 90.0 or 4.0 per serving.

Enter Selection (0 to Exit): 9

Varying the Expenses +/-10%:

Percent: -10 Expenses: 1719.0 Profit/Loss: 281.0

Percent: -8 Expenses: 1757.2 Profit/Loss: 242.8

Percent: -6 Expenses: 1795.4 Profit/Loss: 204.6

Percent: -4 Expenses: 1833.6 Profit/Loss: 166.4

Percent: -2 Expenses: 1871.8 Profit/Loss: 128.2

Percent: 0 Expenses: 1910.0 Profit/Loss: 90.0

Percent: 2 Expenses: 1948.2 Profit/Loss: 51.8

Percent: 4 Expenses: 1986.4 Profit/Loss: 13.6

Percent: 6 Expenses: 2024.6 Profit/Loss: -24.6

Percent: 8 Expenses: 2062.8 Profit/Loss: -62.8

Varying the Income +/-10%:

Percent: -10 Income: 1800.0 Profit/Loss: -110.0

Percent: -8 Income: 1840.0 Profit/Loss: -70.0

Percent: -6 Income: 1880.0 Profit/Loss: -30.0

Percent: -4 Income: 1920.0 Profit/Loss: 10.0

Percent: -2 Income: 1960.0 Profit/Loss: 50.0

Percent: 0 Income: 2000.0 Profit/Loss: 90.0

Percent: 2 Income: 2040.0 Profit/Loss: 130.0

Percent: 4 Income: 2080.0 Profit/Loss: 170.0

Percent: 6 Income: 2120.0 Profit/Loss: 210.0

Percent: 8 Income: 2160.0 Profit/Loss: 250.0

Bonus:

Add functionality that will that use the current expenses and sales volume but

vary the sale price until the "break-even" point is found. If the initial calculation

is positive then reduce the price iteratively and if negative, increase the price

iteratively (think loop). Note that your algorithm doesn't have to find the exact

break even point, only the point where it changes from negative to positive or

positive to negative

10. Find Break-Even

Enter Selection (0 to Exit): 10

Break-Even occurs with a selling price of: 5.7

Note that in all these calculations, assume that the shop operates with a single

employee six days a week, eight hours per day.

# Tip: Always make constants ALL CAPS and give them descriptive names. Think about what

constants you will need in your script. I.e. what numbers will you use that are fixed?

"""

"""

Naming variables well is a best practice. While formats vary by developer/language,

"snake_case" is commonly used in Python. For example, a variable containing the cost

per serving of ice cream could be named serving_cost. Doing this consistently with a

consistent convention is one mark of a professional developer as it reduces the long

term cost of software maintenance by creating "built in" documentation.

What variables will you need? Start out by listing what the script needs (inputs)

and what the script will produce (outputs). Hint: look at the sample menu. List those

out and you'll be well on your way.

"""

"""

Additional Hints:

You'll need some form of loop that the script will stay in until the user chooses option

0 to exit. In this loop, you'll want to print out the menu and prompt for user input.

In this way, everytime a selection is made, the work is done then the loop starts over

and refreshes the menu. Once the user wants to exit, just break out of the loop just like

learned in the text reading.

Next you'll need some logic to either update your variables or to calculate the requested

information.

IDE's support something called "breakpoints" which allow you to stop execution and examine the

of variables in the code. If you don't want to learn that yet then remember you can always put

extra "prints" to output intermediate values to test your algorithms.

Don't forget to comment your code. It's the perfect time to start a good habit!
