An error in stocking out what is the mistake in my code


#1

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 prices:
         if stock[item] > 0:
             total += prices[item]
             stock[item] = stock[item] - 1
    return total

error:Oops, try again. calling compute_bill with a list containing 1 apple, 1 pear and 1 banana resulted in 9 instead of the correct 7


#2

here:

for item in prices:

why do you went back to looping over prices? we determined you need to loop over food (and given you reached that conclusion, i assumed you understood)
