print(pickle.loads(obj) is a) # False print(pickle.loads(obj).a) # aaa # 除此之外,pickle还可以将序列化dump到一个文件里,然后从文件里面load ''' 函数分别是dump和load pickle.dump(python对象, f) pickle.load(f) 和不涉及文件的dumps、loads类似 pickle.dumps(Python对象) -->会有返回值,obj ...

Pickle is unsafe because it can execute malicious Python callables to construct objects. When deserializing an object, Pickle cannot tell the difference between a malicious callable and a non-malicious one. Due to this, users can end up executing arbitrary code during deserialization. As mentioned ...

For now, keep in mind that every Python tool that scans an object from left to right uses the iteration protocol. This is why the sorted call used in the prior section works on the dictionary directly—we don’t have to call the keys method to get a sequence because dictionaries are ...
不如直接用标准的Python方式来处理对象的保存和加载，也就是直接使用pickle.dump和pickle.load。
