您好，我正在創建一個包含購物清單的課程。該代碼似乎有效，但我不確定我是否正確執行。我是否打算將 Shopping = [] 放入構造函數中，那有什么作用？提前謝謝了class Shopping: def __init__(self, shopping = []): self.__shopping = [] def set_shopping(self, shopping): self.__shopping = shopping def get_shopping(self): return self.__shoppingshoppinglist = Shopping()shoppinglist = ['apples', 'pears', 'bread']

這是一個例子：
class Shopping:
def __init__(self, shopping = []):
self.__shopping = []
def set_shopping(self, shopping):
self.__shopping = shopping
def get_shopping(self):
return self.__shopping
def add_article(self, article):
self.__shopping.append(article)
def get_article(self, index):
return self.__shopping[index]
shoppinglist = Shopping()
shoppinglist.set_shopping(['apples', 'pears', 'bread'])
shoppinglist.add_article('oranges')
shoppinglist.get_article(0) #==> 'apples'
shoppinglist.get_article(3) #==> 'oranges'
