version of Python needed to read the pickle produced. The *file* argument must have a write() method that accepts a single bytes argument. It can thus be a file object opened for binary writing, an io.BytesIO instance, or any other custom object that meets this interface. If *fix_impor...
例如XML、Json、Protocol Buffer、msgpack等。 不同的协议,效率不同、学习曲线不同,适用不同场景,要根据不同的情况分析选型。 注:目前有6个版本pickle协议,3.4增加了v4,3.8增加了v5(PEP 574) 回到顶部(go to top) 4、JSON 4.1、简介 JSON(JavaScript Object Notation, JS 对象标记) 是一种轻量级的数据交换...
Pickle是Python中的一个模块,用于将Python中的对象序列化为二进制流并保存到文件中,或者从文件中读取出这些二进制数据并反序列化成对象。这个过程也被称为对象的持久化。 Pickle可以处理几乎所有Python数据类型,包括数字、字符串、列表、元组、字典、类和函数等。使用Pickle可以非常方便地将Python对象存储到文件中,以便...
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...
