Python 如何获取dir未返回的对象的属性列表

dir（OldStyleClass）

不会返回

OldStyleClass

的所有属性。在下面的示例中，旧式类的

dir

实例不返回

\uuuuuuuuuuuuuuuuuuu

：

class OldStyleClass:
    pass

old = OldStyleClass()
dir(old)
['__doc__', '__module__']
print  old.__class__
 __main__.OldStyleClass

---

help（dir）

还表示返回“一些属性”。是否有方法获取对象的属性列表，这些属性不是通过

dir

显示的？

您必须按照类进行操作；

\uuuu class\uuuu

属性是在类型上定义的：

>>> type(OldStyleClass)
<type 'classobj'>
>>> dir(type(OldStyleClass))
['__call__', '__class__', '__delattr__', '__doc__', '__format__', '__getattribute__', '__hash__', '__init__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__']

>类型（OldStyleClass）
>>>目录（类型（OldStyleClass））
“UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU“子类钩子”
