【1.102】面向对象-组合

看看简单的组合

class Hand:
    pass

class Foot:
    pass

class Trunk:
    pass

class Head:
    pass

class Person:
    def __init__(self,id_num,name):
        self.id_num=id_num
        self.name=name
        self.hand=Hand()
        self.foot=Foot()
        self.trunk=Trunk()
        self.head=Head()
p1=Person('111111','alex')

print(p1.__dict__)
# {'id_num': '111111', 'name': 'alex', 'hand': <__main__.Hand object at 0x0000000002205860>, 'foot': <__main__.Foot object at 0x0000000002205898>, 'trunk': <__main__.Trunk object at 0x00000000022058D0>, 'head': <__main__.Head object at 0x0000000002205908>}

上面的代码就是一个组合  就是将手 脚  躯干 头 都组合在一个人当中

 

 

1、组合- 思维练习  创建学习类 还有 课程类

2、这里的练习是在创建课程系统 然后直接展示出来

3、通过在课程里面添加学校的信息    意思就是 哪门课程在哪个学校

class School:
    def __init__(self,name,addr):
        self.name = name
        self.addr = addr
    def recruit_stu(self):
        print("%s - %s 校区正在招生"%(self.name,self.addr))
s1 = School("川大","望江")
s2 = School("川大","江安")
s3 = School("川大","华西")class Course:
    def __init__(self,name,price,academic,school):
        self.name = name
        self.price = price
        self.academic = academic
        self.school = school
        # self.teacher = teacher

# c1 = Course("MBA",100,"2年",)
# c2 = Course("牙科",70,"7年")
# c1 = Course("计算机",50,"4年")
