1. 建立一个汽车类Auto,包括轮胎个数,汽车颜色,车身重量,速度等属性,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属性,并且重新实现方法覆盖加速、减速的方法

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

      self.age = age

print(Person.count)  # 1
3. 创建一个动物类,拥有属性:性别、年龄、颜色、类型 ,
要求打印这个类的对象的时候以'/XXX的对象: 性别-? 年龄-? 颜色-? 类型-?/' 的形式来打印

class Cat(Animal):
   pass


class Dog(Animal):
   pass
a1 = Animal('公', 3, '白色', '哺乳动物')
print(a1)  # /Animal的对象: 性别-公 年龄-3 颜色-白色 类型-哺乳动物/
c1 = Cat('母', 2, '灰白相间', '布偶猫')
print(c1)  # /Cat的对象: 性别-母 年龄-2 颜色-灰白相间 类型-布偶猫/
d1 = Dog('公', 1, '黑', '哈士奇')
print(d1)  # /Dog的对象: 性别-公 年龄-1 颜色-黑 类型-哈士奇/
4. 写一个圆类, 拥有属性半径、面积和周长;要求获取面积和周长的时候的时候可以根据半径的值把对应的值取到。但是给面积和周长赋值的时候,程序直接崩溃,并且提示改属性不能赋值
class Circle:
   pi = 3.141592653589793

   def __init__(self, radius):
      self.radius = radius
      self._area = Circle.pi * self.radius ** 2

print(c1)  # <radius: 10, area: 314.1592653589793, perimeter: 62.83185307179586>

c1.radius = 5
print(c1)  # <radius: 5, area: 78.53981633974483, perimeter: 31.41592653589793>
5. 写一个扑克类, 要求拥有发牌和洗牌的功能(具体的属性和其他功能自己根据实际情况发挥)
