Python：从Animal类到Cat类的全面实现与属性操作

1. 定义一个类animal，包含私有属性name和kind，构造函数中通过形参赋值，定义属性方法getname和getkind，changekind，delkind方法，静态属性kind，对象a1为（parrot，bird）。 ```python class Animal: def __init__(self, name, kind): self.__name = name self.__kind = kind def getname(self): return self.__name def getkind(self): return self.__kind def changekind(self, new_kind): self.__kind = new_kind def delkind(self): del self.__kind kind = "static" a1 = Animal("parrot", "bird") print(a1.getname()) # 输出：parrot print(a1.getname) # 输出：<bound method Animal.getname of <__main__.Animal object at 0x7f8c1c2d3a90>> print(a1.getkind()) # 输出：bird a1.changekind("polytelis") print(a1.getkind()) # 输出：polytelis a1.delkind() ``` 2. 在Animal类中增加一个方法talk，输出i can speak。 ```python class Animal: # ...其他代码... def talk(self): print("I can speak.") ``` 3. 在Animal类中增加一个方法myprint，输出name和kind的值。 ```python class Animal: # ...其他代码... def myprint(self): print("Name:", self.__name, "Kind:", self.__kind) ``` 4. 定义一个类cat，定义私有属性food和enemy，在构造函数中赋值，继承自animal。 ```python class Cat(Animal): def __init__(self, name, kind, food, enemy): super().__init__(name, kind) self.__food = food self.__enemy = enemy ``` 5. 定义talk方法，输出喵喵。 ```python class Cat(Animal): # ...其他代码... def talk(self): print("喵喵") ``` 6. 定义方法catchmouse，输出i catch a mouse. ```python class Cat(Animal): # ...其他代码... def catchmouse(self): print("I catch a mouse.") ``` 7. 定义方法myprint，输出子类对象所有属性。 ```python class Cat(Animal): # ...其他代码... def myprint(self): print("Name:", self.getname(), "Kind:", self.getkind(), "Food:", self.__food, "Enemy:", self.__enemy) ``` 8. 定义animal类对象a2，(octopus, )。 ```python a2 = Animal("octopus", "") ``` ######[AI写代码神器 | 724点数解答 | 2024-06-13 18:40:28]
