Classes And Ice Cream

What will the program output when you run

1 2	`chocolate = IceCream("chocolate",4,1,6) print chocolate.scoop()`

using the below code?

Try to walk through the program in your head to find the answer before you actually run the code.

class IceCream(object):
    def __init__(self, flavor, numScoops, costPerScoop, remaining_icecream):
        self.flavor = flavor
        self.numScoops = numScoops
        self.costPerScoop = costPerScoop
        self.remaining_icecream = remaining_icecream

    def scoop(self):
                #shows the amount of ice cream remaining after an order is scooped
        #scoops icecream and decreases the number of scoops left
        self.remaining_icecream -= self.numScoops
        return self.remaining_icecream

    def total_cost(self):
        #vanilla ice cream is sold at a discount of half off!
        if self.flavor == "vanilla":
            total_cost = self.numScoops * .5*self.costPerScoop

        else:
            total_cost = self.numScoops * self.costPerScoop

        return total_cost

The answer is 2.

The number of scoops available at the beginning is 6. Then the customer orders 4 scoops. 6 - 4 = 2 scoops remaining.

Run the code to verify.

Sorry, but what is the name of programme that uses code?

I'm not sure if I'm understanding your question, but to run this code, copy it into some text editor (or you can do this in a python shell) and save the file as a .py file. You can name it whatever you like as long as it is the form FileName.py. (I named this iceCream.py on my computer).

Oh, Thank you!! :) I just want to know where to run the code. I am quite curious. :)

Why does it return the number of scoops remaining? The last line of code says "return total_cost," so why would it not output the total cost?

total cost is only returned chocolate.total cost() is called. In the code above chocolate.scoop() is called which returns the value of remaining_icecream - numScoops

remaining icecream = 6, numScoops = 4 then self.remaining icecream -= self.numScoops =2

Flavor = Chocolate, remaining_icecream = 6 & numScoops = 4. Number of Scoops remaining is 6 - 4 = 2
