0.定義?個學?類椒惨。有屬性：姓名系洛、年齡、成績（語?蝇狼，數(shù)學，英語)[每課成績的類型為整數(shù)]
?法： a. 獲取學?的姓名：getname() b. 獲取學?的年齡：getage()
c. 返回3?科?中最?的分數(shù)欣硼。get_course()
class Student:

if __name__ == '__main__':
joe = Student('jerry', 18)
print(joe.get_name())
print(joe.get_age())

1.建??個汽?類Auto题翰，包括輪胎個數(shù)恶阴，汽?顏?诈胜，?身重量，速度等成員變量冯事，并通過不同的構造?法創(chuàng)
建實例焦匈。?少要求 汽?能夠加速 減速 停?。 再定義?個?汽?類CarAuto 繼承Auto 并添加空調昵仅、CD等成
員變量 覆蓋加速 減速的?法

2.創(chuàng)建?個名為User 的類缓熟，其中包含屬性firstname 和lastname ，還有?戶簡介通常會存儲的其他?個屬
性摔笤。在類User 中定義?個名 為describeuser() 的?法够滑，它打印?戶信息摘要;再定義?個名為greetuser() 的
?法，它向?戶發(fā)出個性化的問候吕世。
管理員是?種特殊的?戶彰触。編寫?個名為Admin 的類，讓它繼承User類命辖。添加?個名為privileges 的屬性况毅，
?于存儲?個由字符串(如"can add post"、"can delete post"尔艇、"can ban user"等)組成的列表尔许。編寫?個名為
show_privileges()的?法，它顯示管理員的權限终娃。創(chuàng)建?個Admin 實例味廊，并調?這個?法。
class User:
"""用戶類"""
def __init__(self, first_name, last_name, description, hometown):
self.first_name = first_name

super().__init__(first_name, last_name, description, hometown)
self.privilege = privilege
def show_privileges(self):
return '%s' % self.privilege
if __name__ == '__main__':
pass
3.創(chuàng)建?個Person類，添加?個類字段?來統(tǒng)計Perosn類的對象的個數(shù)

self.name = ''
self.age = 0
self.sex = ''
@classmethod

name = input('name:')
age = input('age:')
sex = input('sex:')
person = Person(name, age, sex)
cls.all_person.append(person)
if __name__ == '__main__':

(嘗試)5.寫?個類余佛，其功能是：1.解析指定的歌詞?件的內容 2.按時間顯示歌詞 提示：歌詞?件的內容?般
