而 pickle 是一个二进制序列化格式; JSON 是我们可以直观阅读的,而 pickle 不是; JSON是可互操作的,在Python系统之外广泛使用,而pickle则是Python专用的; 默认情况下,JSON 只能表示 Python 内置类型的子集,不能表示自定义的类;但 pickle 可以表示大量的 Python 数据类型(可以合理使用 Python 的对象内省功能自动...

However, there’s one more thing you need to know about the Python pickle module: It’s not secure. Do you remember the discussion of __setstate__()? Well, that method is great for doing more initialization while unpickling, but it can also be used to execute arbitrary code during the...

关于Pickler类的其他method,请参考官方API。 插播一条硬广:技术文章转发太多,本文来自微信公众号:“Python数据之道”(ID:PyDataRoad)。 3 反序列化操作 3.1 反序列化方法pickle.load() 序列化的方法为 pickle.load(),该方法的相关参数如下: pickle.load(file, *,fix_imports=True, encoding=”ASCII”. errors...

org/pickle-python-object-serialization/pickle 模块用于实现序列化和反序列化 Python 对象结构的二进制协议。酸洗:这是一个将 Python 对象层次转换成字节流的过程。 取消锁定:这是酸洗过程的逆过程,其中字节流被转换为对象层次结构。模块界面:dumps()–调用该函数来序列化对象层次结构。 loads()–调用该函数来反...
pickle --- Python 对象序列化源代码: Lib/pickle.py模块pickle 实现了对一个 Python 对象结构的二进制序列化和反序列化。 "pickling" 是将Python 对象及其所拥有的层次结构转化为一个字节流的过程,而 "unpickling" 是相反的操作,会将(来自一个 binary file 或者bytes-like object 的)字节流转化回一个对象层次...
