copied!<p>I am studying for my final and this was a quiz question I missed. I need most of the help on the getTotal method. I need to loop through the list, find the price of each item, add the price to the total and return the total. I struggle with loops and I am not sure how to pull the second item out of a list.. [1] ?? I have tried many ways and am getting frustrated.</p> <p>If there is anyone up that is willing to help me that would be great. I am still learning and am new at this so go easy on me, but I really want to learn it. It's probably not as hard as I make it out to be, but Ill be waiting for some input. Thank you!</p> <pre><code>class Item: def __init__(self, name, price): self.name = name self.price = price def getPrice(self): return self.price def getName(self): return self.name class Cart: def __init__(self, list): self.list = [] def addItem(self, item): self.list.append(self.list) def getTotal(self): total = 0 for item in self.list: name, price = item # or price = item[1] total = total + price def getNumItems(self): count = 0 for c in range(self.list): count = self.list + 1 return count def removeItem(self, item) #removes the item from the cart's item list def main(): item1 = Item("Banana", .69) item2 = Item("Eggs", 2.39) item3 = Item("Donut", .99) c = Cart() c.addItem(item1) c.addItem(item2) c.addItem(item3) print "You have %i items in your cart for a total of $%.02f" %(c.getNumItems(), c.getTotal()) c.removeItem(item3) print "You have %i items in your cart for a total of $%.02f" % (c.getNumItems(), c.getTotal()) main() </code></pre>
