Let's check out 13/13



It just prints 'none' to the console how do i print the prices and stocks to the console so I can see the work of the 'compute_bill' code?

shopping_list = ["banana", "orange", "apple"]

stock = {
    "banana": 6,
    "apple": 0,
    "orange": 32,
    "pear": 15
prices = {
    "banana": 4,
    "apple": 2,
    "orange": 1.5,
    "pear": 3

# Write your code below!
def compute_bill(food):
    total = 0
    for  item in food:
        if stock[item] > 0:
            total += prices[item] 
            stock[item] = stock[item] - 1
    return total


call the function with print.like

print compute_bill(shopping_list)


hey thanks. It returns 5.5? and when i add pear to the shopping list, it returns 8.5...I'm trying to figure out what is happening when i print compute_bill. Can you give me like a short explanation pls
