- 建立一個汽車類Auto焰盗，包括輪胎個數(shù)觉至，汽車顏色剔应，車身重量，速度等屬性语御，并通過不同的構(gòu)造方法創(chuàng)建實例峻贮。至少要求 汽車能夠加速 減速 停車。 再定義一個小汽車類CarAuto 繼承Auto 并添加空調(diào)应闯、CD屬性纤控，并且重新實現(xiàn)方法覆蓋加速、減速的方法

- 創(chuàng)建一個Person類碉纺，添加一個類字段用來統(tǒng)計Perosn類的對象的個數(shù)
class Person:
count = 0

Person.count += 1
p1 = Person()

print(Person.count) # 3
- 創(chuàng)建一個動物類船万，擁有屬性：性別、年齡骨田、顏色耿导、類型 ，
要求打印這個類的對象的時候以'/XXX的對象: 性別-? 年齡-? 顏色-? 類型-?/' 的形式來打印
class Animal:

ani = Animal('公', 12, '黑色', '狗')
print(ani) #/Animal的對象:性別-公 年齡-12 顏色-黑色 類型-狗/
- 寫一個圓類态贤， 擁有屬性半徑舱呻、面積和周長；要求獲取面積和周長的時候的時候可以根據(jù)半徑的值把對應(yīng)的值取到悠汽。但是給面積和周長賦值的時候箱吕，程序直接崩潰芥驳，并且提示改屬性不能賦值

c1 = Circle(50)

- (嘗試)寫一個類茬高，其功能是：1.解析指定的歌詞文件的內(nèi)容 2.按時間顯示歌詞 提示：歌詞文件的內(nèi)容一般是按下面的格式進行存儲的晚树。歌詞前面對應(yīng)的是時間，在對應(yīng)的時間點可以顯示對應(yīng)的歌詞
