0.定义一个学生类。有属性:姓名、年龄、成绩(语文,数学,英语)[每课成绩的类型为整数]

方法: a. 获取学生的姓名:getname() b. 获取学生的年龄:getage()

c. 返回3门科目中最高的分数。get_course()

class Student:
    def __init__(self,name,age,chinese,math,english):
        self.__name = name
        self.__age = age
        self._chinese = chinese
        self._math = math
        self._english = english
    def getName(self):
        return self.__name
    def getage(self):
        return self.__age
    def get_course(self):
        return max(self._chinese,self._english,self._math)

    @property
    def chinese(self):
        return self._chinese

    @chinese.setter
    def chinese(self,chinese):
        if isinstance(chinese,int):
            raise ValueError
        if not 0<=chinese<=100:
            raise ValueError
        self._chinese = chinese

    @property
    def math(self):
        return self._math

    @math.setter
    def math(self, math):
        if isinstance(math, int):
            raise ValueError
        if not 0 <= math <= 100:
            raise ValueError
        self._math = math

    @property
    def english(self):
        return self._english

    @english.setter
    def english(self, english):
        if isinstance(english, int):
            raise ValueError
        if not 0 <= english <= 100:
            raise ValueError
        self._english = english

student = Student("老刘",20,80,85,75)
print(student.chinese)
print(student.getName())
print(student.getage())
print(student.get_course())

1.建立一个汽车类Auto,包括轮胎个数,汽车颜色,车身重量,速度等成员变量,并通过不同的构造方法创建实例。至少要求 汽车能够加速 减速 停车。 再定义一个小汽车类CarAuto 继承Auto 并添加空调、CD等成员变量 覆盖加速 减速的方法

class Auto:
    def __init__(self,tyre,color,weight,speed):
        self.tyre = type
        self.color = color
        self.weight = weight
        self.speed = speed
    def speedUp(self):
        self.speed += 1
        return '速度+1'
    def speedDown(self):
        self.speed -= 1
        return '速度-1'
    def speedStop(self):
        self.speed = 0
        return '停止'
class CarAuto(Auto):
    def __init__(self,tyre,color,weight,speed,airAonditioner,cd):
        super().__init__(tyre,color,weight,speed)
        self.airAonditioner = airAonditioner
        self.cd = cd

carAuto = CarAuto(5,'white','2000kg',60,'美的','飞翔')
print(carAuto.speedUp())
print(carAuto.speedDown())
print(carAuto.speedStop())
print(carAuto.airAonditioner)
print(carAuto.cd)

2.创建一个名为User 的类,其中包含属性firstname 和lastname ,还有用户简介通常会存储的其他几个属性。在类User 中定义一个名 为describeuser() 的方法,它打印用户信息摘要;再定义一个名为greetuser() 的方法,它向用户发出个性化的问候。

管理员是一种特殊的用户。编写一个名为Admin 的类,让它继承User类。添加一个名为privileges 的属性,用于存储一个由字符串(如"can add post"、"can delete post"、"can ban user"等)组成的列表。编写一个名为show_privileges()的方法,它显示管理员的权限。创建一个Admin 实例,并调用这个方法。

class User:
    def __init__(self,firstname,lastname,age,hobby,university):
        self.firstname = firstname
        self.lastname = lastname
        self.age = age
        self.hobby = hobby
        self.university = university
    def describeuser(self):
        return self.lastname+'曾经用过:'+self.firstname+'的名字,今年'+str(self.age)+'岁,喜欢'+self.hobby+',毕业于'+self.university
    def greetuser(self):
        return '亲爱的'+self.lastname+'你好,听说'+self.hobby+'的人都很帅~~~'
class Admin(User):
    def __init__(self,firstname,lastname,age,hobby,university,privileges=["can add post","can delete post","can ban user"]):
        super().__init__(firstname,lastname,age,hobby,university)
        self.privileges = privileges
    def show_privileges(self):
        return self.privileges

admin = Admin('Randy','Wildpigger',21,'唱歌','小野猪野生学院',["can add post","can delete post"])
print(admin.describeuser())
print(admin.greetuser())
print(admin.show_privileges())

3.创建一个Person类,添加一个类字段用来统计Perosn类的对象的个数

class Person:
    num = 0
    def __init__(self,name):
        Person.num += 1
        self.name = name
        print(self.name+'是第'+ str(Person.num) +'个创建的对象~~~')

    @classmethod
    def personNums(self):
        return '总共'+str(Person.num)+'个人~~'

p1 = Person('老刘')
p2 = Person('老曾')
p3 = Person('老余')
print(Person.personNums())

(尝试)5.写一个类,其功能是:1.解析指定的歌词文件的内容 2.按时间显示歌词 提示:歌词文件的内容一般是按下面的格式进行存储的。歌词前面对应的是时间,在对应的时间点可以显示对应的歌词

[00:00.20]蓝莲花

[00:06.53]你对自由地向往
