1.定義類別: 初始化屬性、被考核添加條掉的方法，顯示對象的信息str

class SweetPotato():
def init(self):
# 烤的時間
self.cook_time = 0
# 地瓜的狀態
self.cook_state = '生的'
# 調料列表
self.condiments = []

def cook(self, time):
    """烤地瓜的方法"""
    # 烤的時間，狀態
    self.cook_time += time
    if 0 <= self.cook_time < 3:
        self.cook_state = '生的'
    elif 3 <= self.cook_time < 5:
        self.cook_state = '半生不熟'
    elif 5 <= self.cook_time < 8:
        self.cook_state = '熟了'
    else:
        self.cook_state = '燒焦了'

def add_condiments(self, condiment):
    """用戶意願的調料追加到調料列表"""
    self.condiments.append(condiment)

def __str__(self):
    return f"這個地瓜總共烤了{self.cook_time}分鐘，狀態是{self.cook_state},調料有{self.condiments}"

2.創建對象，並調用對應的方法

i = 0
while i < 8:
sweetPotato = SweetPotato()
time = int(input('預烤時間為:'))
sweetPotato.cook(time)

condiment = input('調料為:')
sweetPotato.add_condiments(condiment)

print(sweetPotato)
i += time
