0}. 建立一個汽車類Auto，包括輪胎個數(shù)哈垢，汽車顏色妻柒，車身重量，速度等屬性耘分，并通過不同的構(gòu)造方法創(chuàng)建實例举塔。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)求泰、CD屬性啤贩，并且重新實現(xiàn)方法覆蓋加速、減速的方法

class Auto:
    def __init__(self, weight, speed, tyre_num= 4, color = 'white'):
        self.weight = weight
        self.tyre_num = tyre_num
        self.color = color
        self.speed = speed

    def speed_up(self):
        self.speed+=5
        print('當(dāng)前速度：%skm/h'%(self.speed))

    def speed_down(self):
        self.speed-=5
        print('當(dāng)前速度：%skm/h'%(self.speed))


class CarAuto(Auto):

    def __init__(self,*args,**kwargs) :
        super().__init__(*args,**kwargs)
        self.air_conditioner = 'air_conditioner'
        self.CD = 'CD'

    def speed_up(self):
        self.speed += 10
        print('當(dāng)前速度：%skm/h' % (self.speed))

    def speed_down(self):
        self.speed -= 10
        print('當(dāng)前速度：%skm/h' % (self.speed))


car1 = CarAuto('1200KG',80)
print(car1.color,car1.tyre_num,car1.speed)
car1.speed_down()
car1.speed_down()
car1.speed_up()

{0}. 創(chuàng)建一個Person類拜秧，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
    def __init__(self):
        Person.count += 1

p1 = Person()
P2 = Person()
p3 = Person()
print(Person.count)

{0}. 創(chuàng)建一個動物類痹屹，擁有屬性：性別、年齡枉氮、顏色志衍、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:
    def __init__(self,gender,age,color,kinds):
        self.gender = gender
        self.age = age
        self.color = color
        self.kinds = kinds

    def __repr__(self):
        return '{}對象：性別：{}年齡：{}顏色：{}品種：{}'.format(self.__class__.__name__,self.gender,self.age,self.color,self.kinds)

animal1 = Animal('雄',18,'white','羊')
print(animal1)

{0}. 寫一個圓類聊替， 擁有屬性半徑楼肪、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)的值取到惹悄。但是給面積和周長賦值的時候春叫，程序直接崩潰，并且提示改屬性不能賦值

class Circle:
    pi = 3.1415926
    def __init__(self,r,c = None,area = None):
        self.r = r
        self._c = c
        self._area = area

    @property
    def c(self):
        if self._c == None:
            self._c = self.r * Circle.pi * 2
            return self._c
        else:
            print('周長不能直接賦值')
            raise str(ValueError)

    @property
    def area(self):
        if self._area == None:
            self._area = ((self.r)**2) * Circle.pi
            return self._area
        else:
            print('面積不能直接賦值')
            raise ValueError

c1 = Circle(5)
print(c1.r,c1.c,c1.area)
c2 = Circle(2,6.28,100)
print(c2.area,c2.c)

{0}. 寫一個撲克類泣港， 要求擁有發(fā)牌和洗牌的功能(具體的屬性和其他功能自己根據(jù)實際情況發(fā)揮)

class Onepear:
