Making a Purchase


I'm not sure how to add the price of the item. can someone help
Oops, try again. compute_bill(['apple']) resulted in a TypeError: unsupported operand type(s) for +: 'int' and 'str'

Replace this line with your 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:
        total = total + item
    return total


item is a string. We cannot add a string to a number. What you want to add is the value associated with that key.
