I want my class to implement Save and Load functions which simply do a pickle of the class. But apparently you cannot use 'self' in the fashion below. How can you do this?
self = cPickle.load(f)
This is what I ended up doing. Updating the
__dict__ means we keep any new member variables I add to the class and just update the ones that were there when the object was last pickle'd. It seems the simplest while maintaining the saving and loading code inside the class itself so calling code just does an object.save().
def load(self): f = open(self.filename, 'rb') tmp_dict = cPickle.load(f) f.close() self.__dict__.update(tmp_dict) def save(self): f = open(self.filename, 'wb') cPickle.dump(self.__dict__, f, 2) f.close()
