\__getattribute__和__getattr__
==================================

属性存在时调用__getattribute__，不存在时(或者在__getattribute__抛出AttributeError)调用__getattr__


\__name__和__qualname__
======================================

``__qualname__`` 返回某个类、函数或方法的 `限定名称 <https://docs.python.org/zh-cn/3/glossary.html#term-qualified-name>`_ (指完整的调用路径, 如)

``__name`` 仅返回名称

.. code-block:: pycon

    >>> class C:
    ...    class D:
    ...        def meth(self):
    ...            pass

    >>> C.__qualname__
    'C'
    >>> C.D.__qualname__
    'C.D'
    >>> C.D.meth.__qualname__
    'C.D.meth'
    >>> C.D.meth.__name__
    'meth'
