TypeError: __getattribute__() missing 1 required positional argument: 'value'

Question

w = c.WriteOnly()
w.l #classes.OprationError

但是

Traceback (most recent call last):
  File "<pyshell#46>", line 1, in <module>
    w.l
TypeError: __getattribute__() missing 1 required positional argument: 'value'

附WriteOnly源码(测试)

class WriteOnly(object):
    def __getattr__(self, name):
        raise OprationError('Cannot get attribute')
    
    def __getattribute__(self, name):
        raise OprationError('Cannot get attribute')

Answer 1

class WriteOnly(object):
    def __getattr__(self, name):
        raise SystemError('Cannot get attribute')

    def __getattribute__(self, name):
        raise SystemError('Cannot get attribute')


w = WriteOnly()
w.l

稍微改了一下,跑出来是这个效果
