视频的例子中，“class MikMixin”里面不是有属性吗？“temperature, volume”这些不是属性吗？

1.小试牛刀： class AddMixin(): #此类为添加东西的类 def addliquid(self,liquid,nums,temp): #此方法用于加液体 self.liquid=liquid self.volume=nums if temp=="cold": self.temperature="cold" elif temp=="hot": self.temperature="hot" return f"add {self.temperature} {self.liquid} {self.volume} ML" class Coffee(AddMixin): #此类为咖啡 def __init__(self,water=1,water_temp="hot",milk=1,milk_temp="hot",coffee=1,coffee_temp="hot"): self.water=water self.water_temp=water_temp self.milk=milk self.milk_temp=milk_temp self.coffee=coffee self.coffee_temp = coffee_temp self.prescription=[] if int(self.water)>0: self.prescription.append(super().addliquid("water",self.water,self.water_temp)) if int(self.milk) > 0: self.prescription.append(super().addliquid("milk", self.milk, self.milk_temp)) if int(self.coffee) > 0: self.prescription.append(super().addliquid("coffee", self.coffee, self.coffee_temp)) def showPrescription(self): for i in self.prescription: print(i) #实例化一杯拿铁 latte=Coffee(water=50,water_temp="hot",milk=300,milk_temp="hot",coffee=150,coffee_temp="hot") latte.showPrescription() 2.输出内容 add hot water 50 ML add hot milk 300 ML add hot coffee 150 ML
