day31 类的组合及继承，文件目录规范

Posted 2020-09-26 何必从头

Python之路，Day18 = Python基础18-面向对象继承与组合

 

类的继承

 1 def talk():
 2     print("I am come from talk..a")
 3 
 4 class Animal:
 5     def say(self):
 6         print("say")
 7 
 8 class Person(object):
 9     def __init__(self, name, age):
10         self.name = name
11         self.age = age
12 
13     def walk(self):
14         print("%s is walking..."%self.name)
15 
16 class Teacher(Person):
17     def say(self):
18         Animal.say(123)
19     pass
20 
21 class Student(Person):
22     def __init__(self, name, age, tuition):
23         Person.__init__(self, name, age)
24         self.tuition = tuition
25 
26     def walk(self):
27         Person.walk(self)
28         print("I am come from Student...")
29 
30     def talk(self):
31         talk()                     # 对象可以调用外面的函数
32 
33 t = Teacher(\'zhang\', 18)
34 print(t.name, t.age)
35 t.walk()
36 t.say()
37 
38 
39 s = Student(\'liu\', 17, 19800)
40 print(s.name, s.age)
41 s.walk()
42 print(s.tuition)
43 
44 
45 s.talk()

 

类的组合

 1 class BirthDay(object):
 2     def __init__(self, year, mon, day):
 3         self.year = year
 4         self.mon = mon
 5         self.day = day
 6 
 7     def tellInfo(self):
 8         print("comes from BirthDay")
 9         return "year:%s  mon:%s  day:%s"%(self.year, self.mon, self.day)
10 
11 
12 class Teacher(object):
13     def __init__(self, name, age, sex, birth):
14         self.name = name
15         self.age = age
16         self.sex =sex
17         self.birth = birth
18 
19 
20 
21 t = Teacher(\'zhang\', 18, \'male\', BirthDay(1999, 9, 99))
22 
23 print(t.birth.tellInfo())
