作业：

1、编写一个Dog类,并生成对象dog,属性包含颜色，大小，重量，可以汪汪叫，摇尾巴，跑

# -*- coding: utf-8 -*-


class Dog:
    def __init__(self, color, size, weight):
        self.color = color
        self.size = size
        self.weight = weight

    def wangwang(self):
        text = "dog color:{},size:{},wieght:{} wangwang".\
            format(self.color, self.size, self.weight)
        print(text)

    def shaketail(self):
        print("dog shake tail.")

    def run(self):
        print("dog run.")


dog = Dog("white", 20, 5)
dog.wangwang()
dog.shaketail()
dog.run()

 

2、编写一个Cat类，并生成cat对象，属性包含颜色，年龄，重量，可以喵喵叫，可以捉老鼠，会爬树

# -*- coding: utf-8 -*-


class Cat:
    def __init__(self, color, age, weight):
        self.color = color
        self.age = age
        self.weight = weight
        self.mouse_count = 0

    def miaomiao(self):
        print("miao miao")

    def catch_mouse(self):
        self.mouse_count += 1
        print("catch a mouse, have mouse count:", self.mouse_count)

    def climb_tree(self):
        print("cat climb tree.")


cat = Cat("white", 3, 2)
cat.miaomiao()
cat.catch_mouse()
cat.climb()
cat.catch_mouse()
