python之對象組合

標籤：__init__   分配   老師   student   python   組合   通過   特性   bsp   

對象的組合又叫嵌套或建模，是通過不同類之間的對象相互賦值完成的，具體如下面的例子

 

class School():    def __init__(self,name,addr):        self.name=name        self.addr=addr    def speech(self):        passsch1=School("北京","昌平區沙河")sch2=School("上海","景寧區")sch3=School("深圳","某某區")class Student():    def __init__(self,name,age,salary):        self.name=name        self.age=age        self.__slary=salarystu1=Student("劉能",‘22‘,12000)stu2=Student("張一山",‘25‘,13000)stu3=Student("趙本山",‘55‘,50000)stu4=Student("劉德華",‘55‘,60000)#下面通過執行個體的賦值進行嵌套# ############## 老師分配校區stu1.school=sch1stu2.school=sch2stu3.school=sch3stu4.school=sch3print(stu1.school.name) #因為已經完成了嵌套，stu1.school有了School類執行個體的特性print(stu1.school.addr)print(stu1.school.speech())
