我想我可能沒有清楚地解釋我的問題。我為此道歉。我會再試一次。我有一個具有某些屬性的父類：class Restaurant():'This is the restaurant class'def __init__(self, name, cuisine_type): self.name = name self.cuisine_type = cuisine_type然后我有一個子類繼承父類的所有屬性并添加一個新的：class IceCreamStand():def __init__(self, *flavor): 'Attributes of parent class initialised' self.flavor = flavor現在我嘗試打印存儲在屬性 flavor 中的口味列表：def desc_flavor(self): print('This Ice_Cream shop has ' + self.flavor + ' flavors')flavor1 = IceCreamStand('Mango', 'Raspberry', 'Coffee', 'Vanilla')如果我使用 concat，我會收到一條消息，指出名稱未定義。對于第一次沒有正確解釋問題，我深表歉意，并感謝您的所有幫助。

class IceCreamStand(Restaurant):
def __init__(self,restaurant_name, cuisine_type):
super().__init__(restaurant_name, cuisine_type)
def describe_flavors(self,*flavors):
print(f'{self.restaurant_name} has the following flavors:')
for self.flavor in flavors:
print(f'-{self.flavor}')
restaurant =IceCreamStand('DQ','ice cream')
restaurant.describe_restaurant()
restaurant.describe_flavors('Chocolate','Mango', 'Raspberry', 'Coffee', 'Vanilla')

據我所知，您正在做 Python 速成課程第 9 章的練習。這是我作為另一個練習的一部分所做的代碼。希望這對你有幫助。
class Restaurant():
"""A simple attempt to model a restaurant."""
def __init__(self, restaurant_name, cusisine_type):
self.name = restaurant_name
self.type = cusisine_type
def describe_restaurant(self):
print("Restaurant name is " + self.name.title() + ".")
# print(self.name.title() + " is a " + self.type + " type restaurant.")
def open_restaurant(self):
print(self.name.title() + " is open!")
class IceCreamStand(Restaurant):
"""Making a class that inherits from Restaurant parent class."""
def __init__(self, restaurant_name, cusisine_type):
super().__init__(restaurant_name, cusisine_type)
self.flavor = 'chocolate'
def display_flavors(self):
print("This icrecream shop has " + self.flavor + " flavor.")
# create an instance of IceCreamStand
falvors = IceCreamStand('baskin robbins', 'icecream')
# print("My restaurant name is: " + falvors.name)
# print("Restaurant is which type: " + falvors.type)
falvors.describe_restaurant()
falvors.open_restaurant()
# Calling this method
falvors.display_flavors()
