- 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⻔科⽬中最⾼的分数。 get_course()
class Student:
def __init__(self,name,age,chinese_score,math_score,english_score):
self.name = name
self.age = age
self.chinese_score = chinese_score
self.math_score = math_score
self.english_score = english_score
def get_name(self):
print(self.name)
def get_age(self):
print(self.age)
def get_course(self):
lists = [self.chinese_score,self.math_score,self.english_score]
print(max(lists))
stu1 = Student('xzq',18,89,90,10)
stu1.get_name()
stu1.get_age()
stu1.get_course()

- 1.建⽴⼀个汽⻋类Auto，包括轮胎个数，汽⻋颜⾊，⻋身重量，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 汽⻋能够加速 减速 停⻋。 再定义⼀个⼩汽⻋类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 = tyre
self.color = color
self.weight = weight
self.speed = speed
def speed_up(self):
print('汽车正在加速！')
def speed_down(self):
print('汽车正在减速！')
def stop(self):
print('汽车已停车！')
class CarAuto(Auto):
def __init__(self,air_conditioner='',CD=''):
super().__init__(tyre='',color='',weight='',speed='')
self.air_conditioner = air_conditioner
self.CD = CD
def speed_up(self):
print('汽车正在加速！')
def speed_down(self):
print('汽车正在减速！')
def stop(self):
print('汽车已停车！')
car1 = CarAuto(10,20)

- 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):
self.firstname = firstname
self.lastname = lastname
def describeuser(self):
print('用户信息：%s %s'% (self.firstname,self.lastname))
def greetuser(self):
print('%s你好啊'% self.lastname)
class Admin(User):
def __init__(self,privileges=[]):
super().__init__(firstname='',lastname='')
self.privileges = []
def show(self):
self.__show_privileges()
@classmethod
def __show_privileges(cls):
print('管理员，你好')
ad1 = Admin('i can do it')
ad1.show()

- 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:
number = 0
def __init__(self):
Person.number += 1
@classmethod
def numbers(cls):
return cls.number
a =Person()
b =Person()
c =Person()
print(Person.numbers())

- (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
[00:00.80]没有什么能够阻挡
[00:06.53]你对⾃由地向往
[00:11.59]天⻢⾏空的⽣涯

[02:21.81][02:00.60][00:32.30]当你低头地瞬间
[02:26.79][02:05.72][00:37.16]才发觉脚下的路
[02:32.17][00:42.69]⼼中那⾃由地世界
