Python将属性存储在字典中。您可以将属性添加到
MyClass，看到它具有
__dict__：
>>> class MyClass(object):>>> pass>>> dir(MyClass)['__class__', '__delattr__', '__dict__', '__doc__', '__format__', '__getattribute__', '__hash__', '__init__', '__module__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', '__weakref__']
重要的区别是
object没有
__dict__属性。
>>> dir(object)['__class__', '__delattr__', '__doc__', '__format__', '__getattribute__', '__hash__', '__init__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__']
