PYTHON LANGUAGE Design a program that asks for the number of fat grams and calories in a food item. Validate the input as follows: Make sure the number of fat grams and calories is not less than 0. According to nutritional formulas, the number of calories cannot exceed fatGrams×9. Make sure that thenumber of calories entered is not greater than fatGrams×9Once correct data has been entered, the program should calculate and display the percentage of calories thatcome from fat. Use the following formula:Percentageofcaloriesfromfat=(Fatgrams×9)÷CaloriesSome nutritionists classify a food as “low fat” if less than 30 percent of its calories come from fat. If the resultsof this formula are less than 0.3, the program should display a message indicating the food is low in fat
