Making a purchase


#1



Oops, try again. compute_bill(['apple']) resulted in a TypeError: unsupported operand type(s) for +=: 'int' and 'str


Is price supposed to be in this code?


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 += prices[item] * item
    return total

Yes, but the above is not.
