请给 Animal类添加一个类属性 count，每创建一个实例，count 属性就加 1，这样就可以统计出一共创建了多少个 Animal的实例。
# Enter a code class Animal(object): count = 0 def __init__(self, name, age): Animal.count += 1 self.name = name self.age = age dog = Animal('xiaohuang', 5) cat = Animal('mimi', 3) print Animal.count##类属性也是可以动态添加和修改的，需要注意的是，因为类属性只有一份

tuple list 为什么是读取不成功， 重新看下 tuple 与list。

__count的意思是把count改为私有，实例、类都无法直接在def外部访问__count，是俩横线。报错为没有__count这个属性。

Animal.count+=1
是Animal.count=Animal.count+1的意思
