今天是30天程序语言研究的第十二天，研究的语言一样是python,今天主要学习的是物件函式和继承

笔记：

物件函式

class Phone:
def init(self, os, number, is_waterproof): #初始函数
self.os = os
self.number = number
self.is_waterproof
def is_ios(self): #self代表物件本身
if seld.os == "ios":
return True
else:
return False
def add(self, number1, number2):
return number1+number2

phone1 = Phone("ios", 123, True)
print(phone1.is_ios()) #回传true
print(phone1.add(5,6)) #11

继承

class Person:
def init(self, name, age):
self.name = name
self.age = age

def print_name(self):
    print(self.name)
def print_age(self):
    print(self.age)

class Student:
def init(self, name, age, school):
self.name = name
self.age = age
self.school = school

def print_name(self):
    print(self.name)
def print_age(self):
    print(self.age)
def print_school(self):
    print(self.school)

#内容很像可以学生继承人 改class Student如下
from person import Person
class Student(Person):
#相当於复制一份Ｐerson的内容到个位置
def init(self, name, age, school):
self.name = name
self.age = age
self.school = school

def print_school(self):
    print(self.school)

#测试
from student import Student
student1 = Student("小白", 87, "小白国小")
student1.print_school()
student1.print_name()
