小编use*_*686的帖子

我的问题是：

class A(object):
    def __init__(self):
        #init
    def __setstate__(self,state):
        #A __setstate__ code here            
    def __getstate__(self):
        #A __getstate__ code here
        return state

class B(A):
    def __init__(self):
        #creates many object variables here

A 来自外部库。

硬解

我想避免这种情况

当 pickle B 时，pickle 当然使用 A 类的__setstate__方法__getstate__，所以为了让 pickle 工作，我应该这样做：

class B(A):
    def __init__(self):
        #creates many object variables here

    def __setstate__(self,state)
        A.__setstate__(self,state)
        #B __setstate__ code here
        #getting various variables from state for example
        self._a0 = state['a0']
        self._a1 = state['a1']
        #...
        self._a100 = state['a100']
        self._a101 …
