类对象: 就是类本身

实例对象: 由类实例化出来的对象

In [3]: class Animals():
   ...: 	def __init__(self):
   ...: 	self.word = "You are a cat."
   ...: 


In [4]: print(Animals)
<class '__main__.Animals'>


In [5]: a = Animals()


In [6]: print(a)
<__main__.Animals object at 0x000001F67AF06D30>


In [7]: b= Animals


In [8]: print(b)
<class '__main__.Animals'>

里面的Animals就是类对象,a就是这个类的实例对象。
