自己的学习笔记:

#!/usr/bin/python
class Bird(object):  #Bird类继承之object,object是各个类的父类
    have_feather = True
    way_of_reproduction = 'egg'

    def move(self, dx, dy):  #行为方法:move,第一个参数必须是self,其实改成xx也能运行
        position = [0, 0]    #self是供内部使用的
        position[0] += dx
        position[1] += dy
        return position

summer = Bird()
print (summer.way_of_reproduction)
print ('after move:',summer.move(5, 6))


class Chicken(Bird):  #Chicken继承之Bird,它有Bird的所有属性
    way_of_move = 'walk'  #又增加了way_of_move和possible_in_KFC属性
    possible_in_KFC = True
class Oriole(Bird):
    way_of_move = 'fly'
    possible_in_KFC = False

summer = Chicken()
print (summer.have_feather)
print (summer.move(5, 8))

和C++同样具有属性和方法,有继承的属性,还有封装和多态属性吗?
