阅读咸菜文档后,我得到了一个类需要实施的印象__reduce__或__getstate__得到正确腌制.但是,字典的酸洗工作呢？他们没有任何这些属性:
> dict(a=1).__reduce__()
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
/home/daniyar/work/Apr24/<ipython-input-30-bc1cbd43305b> in <module>()
----> 1 dict(a=1).__reduce__()
/usr/lib/python2.6/copy_reg.pyc in _reduce_ex(self, proto)
68 else:
69 if base is self.__class__:
---> 70 raise TypeError, "can't pickle %s objects" % base.__name__
71 state = base(self)
72 args = (self.__class__, base, state)
TypeError: can't pickle dict objects
> dict(a=1).__getstate__()
---------------------------------------------------------------------------
AttributeError Traceback (most recent call last)
/home/daniyar/work/Apr24/<ipython-input-31-00932fb40067> in <module>()
----> 1 dict(a=1).__getstate__()
AttributeError: 'dict' object has no attribute '__getstate__'
另外,从dict派生的类是如何被腌制的？
