2019年7月1日 面向对象设计2 垃圾分类第一天

面向对象设计:OOD  将一类具体事物的数据和动作整合到一起。

面向对象编程:OOP 用定义类+实例/对象的方式去实现面向对象设计。

eg:

学校类:

特征:name,addr,type
动作:考试,招生,开除学生

def school(name,addr,type):#将相关东西放在同一个作用域内
    def init(name,addr,type):#将学校进行初始化
        school1={
            'name':name,
            'addr':addr,
            'type':type,
            'test':test,
            'job':job,
        }
        return school1

    def test(school):
        print('%s we are having a test' % school['name'])

    def job(school):
        print('%s %s we are jobbing' % (school['name'],school['type']))


    return init(name,addr,type)
s1=school('oldboy','shanghai','school')
s1['test'](s1)
print(s1)

s2=school('qinghua','beijing','school')
print(s2)
s2['job'](s2)

>>>

oldboy we are having a test
{'name': 'oldboy', 'addr': 'shanghai', 'type': 'school', 'test': <function school.<locals>.test at 0x101888e18>, 'job': <function school.<locals>.job at 0x10189d048>}
{'name': 'qinghua', 'addr': 'beijing', 'type': 'school', 'test': <function school.<locals>.test at 0x10189d0d0>, 'job': <function school.<locals>.job at 0x10189d158>}
qinghua school we are jobbing
