How do I go through the while loop until I get n=0 and add up the cost of each layer to give me the-CodePudding

def get_pizza_cake_cost(base_diameter, height_per_level):
    n = base_diameter
    while n > 0:
        cost = get_pizza_area(n) * height_per_level * PIZZA_CAKE_COST_PER_CENTIMETRE_CUBED
        n = n - 1
    return cost

enter image description here

if you look at the shell here, i would like the function to return the sum of those two values

Change the existing line to cost = get_pizza_area(n) * height_per_level * PIZZA_CAKE_COST_PER_CENTIMETRE_CUBED

    def get_pizza_cake_cost(base_diameter, height_per_level):
        n = base_diameter
        while n > 0:
            cost  = get_pizza_area(n) * height_per_level * PIZZA_CAKE_COST_PER_CENTIMETRE_CUBED
            n = n - 1
        return cost

well, it does not necessarily depend on your data type, but it helps depict better, your situation. Example: for an array of ints that represent cost n = 10: ->

sum = 0;
while (n>0){
    sum  = arr[n];
    n -= 1;
}
return sum;
