面向對象：

1. 烤麵包

class Bread:
    #定義初始化方法
    def __init__(self):
        self.cookedlevel = 0
        self.cookedstr = '生的'
        self.sauce = []#調味料
    def __str__(self):
        msg = self.cookedstr + '麵包'
        if len(self.sauce) > 0:
            msg = msg + '('
            
            for temp in self.sauce:
                msg = msg + temp + ', '
            msg = msg.strip(', ')#去掉字元串尾部“, ”
            msg = msg + ')'
        return msg
    def cook(self, time):
        self.cookedlevel += time
        if self.cookedlevel > 10:
            self.cookedstr = '焦的'
        elif self.cookedlevel > 7:
            self.cookedstr = '熟的'
        elif self.cookedlevel > 4:
            self.cookedstr = '半熟'
        else:
            self.cookedstr = '生的'
    def addsauce(self, sauce):
        self.sauce.append(sauce)
        
        
bread1 = Bread()
print('一團麵粉：')
print(bread1.cookedlevel)
print(bread1.cookedstr)
print(bread1.sauce)

print('做麵包…………烤麵包')
print('4 min 後：')
bread1.cook(4)
print(bread1)

print('6 min 後：')
bread1.addsauce('奶油')
bread1.cook(6)
print(bread1)

print('11 min 後：')
bread1.addsauce('芝麻')
bread1.cook(11)
print(bread1)

2. 存傢具

class Home:

    def __init__(self, area):
        self.area = area
        self.furniture = []
        

    def __str__(self):
        msg = '當前房間可用面積為：' + str(self.area)
        if len(self.furniture) > 0:
            msg += '容納物品為：'
            for temp in self.furniture:
                msg += temp.getname() + ', '
            msg = msg.strip(', ')
        return msg
        
    def contain(self, item):
        needarea = item.getarea()
        if self.area > needarea:
            self.furniture.append(item)
            self.area -= needarea
            print('存儲 OK')
        else:
            print('錯誤')
    
    
class Bed:
    def __init__(self, area, name = '床'):
        self.area = area
        self.name = name
        
    def __str__(self):
        msg = '床的面積為：' + str(self.area)
        return msg
        
    def getname(self):
        return self.name
    
    def getarea(self):
        return self.area
        
        
myhome = Home(100)
print(myhome)

print('-'*50)

mybed = Bed(20)
print(mybed)

myhome.contain(mybed)
print(myhome)

print('-'*50)

mybed2 = Bed(30, '絨棉床')
print(mybed2)

myhome.contain(mybed2)
print(myhome)
