Enter the item price:
3
Enter the item quantity:
1

Item 2
Enter the item name:

Enter the item quantity:
10

Chocolate Chips 1 @ $3 = $3
Bottled Water 10 @ $1 = $10

Total: $13

Answer 1

#Declare the class ItemToPurchase
class ItemToPurchase:

        #Parameter Constructor
        def __init__(self, item_name='none', item_price=0, item_quantity=0):
                self.item_name = item_name
                self.item_price = item_price
                self.item_quantity = item_quantity

        #Implement the method
        def print_item_cost(self):
                #print the output in a specifed format
                string = '{} {} @ ${} = ${}'.format(
                        self.item_name, self.item_quantity, self.item_price,
                        (self.item_quantity * self.item_price))
                cost = self.item_quantity * self.item_price
                return string, cost

items = []
for i in range(2):
        print('Item', i+1)
        item_name = input('Enter the item name:')
        item_price = int(input('Enter the item price:'))
        item_quantity = int(input('Enter the item quantity:'))          
        items.append(ItemToPurchase(item_name, item_price, item_quantity).print_item_cost())
        print()

print('TOTAL COST')
print(items[0][0])
print(items[1][0])


totalAmount = items[0][1] + items[1][1]
print('Total: $' + str(totalAmount))
