The Program

Write a program in pseudocode and python to calculate the percentage of fat calories in a food

item. Your program should allow the total number of calories in the food item and the

number of grams of fat. Validate the input as follows:

Make sure the number of calories and the number of fat grams are not less than $0.$

There are $9$ calories in every gram of fat. The calories from fat must not exceed the total calories in the food item. Make sure that the number of

calories entered is not greater than fat grams times $9.$

Tell the user if the item is a low$-$fat food item. A low$-$fat food gets $30\%$ or less of its calories from fat.

Round the percentage of calories from fat to two digits to the right of the decimal point.

Here's an example of what you program should look like:

$**$ James Shoe $**$

How many calories per serving?

$240$

How many grams of fat?

$5$

$18\mathrm{.}75\%$ of calories from fat. This is a low fat food.

$**$ James Shoe $**$

How many calories per serving?

$-240$

Number of calories must more than zero.

How many calories per serving? $240$

How many grams of fat?

$-5$

Number of grams of fat must not be negative and calories

from fat cannot exceed the total calories.

How many grams of fat?

$30$

Number of grams of fat must not be negative and calories

from fat cannot exceed the total calories.

How many grams of fat?

$5$

$18\mathrm{.}75\%$ of calories from fat. This is a low fat food.
