所以我有這個(gè)代碼： stock = {    "banana": 6,    "apple": 0,    "orange": 32,    "pear": 15}prices = {    "banana": 4,    "apple": 2,    "orange": 1.5,    "pear": 3}def compute_bill(food):    total = 0    for item in food:        item = shopping_list(prices[key])        total += item    return totalshopping_list = ["pear", "orange", "apple"] total = sum([ prices[s] for s in shopping_list ])print("Items Purchased")print("---------------")for items in shopping_list:    print(items.title() + " @" + )print("---------------")print("Total: ￡{:.2f}".format(total))我想知道我是否能夠打印出每件商品的價(jià)格，正如你所看到的，我已經(jīng)嘗試過(guò)但沒(méi)有成功。
