Pickle 协议和 JSON (JavaScript Object Notation) 间有着本质的不同: JSON 是一个文本序列化格式(它输出 unicode 文本,尽管在大多数时候它会接着以 utf-8 编码),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,

11.1.3. Module Interface To serialize an object hierarchy, you first create a pickler, then you call the pickler’s dump() method. To de-serialize a data stream, you first create an unpickler, then you call the unpickler’s load() method. The pickle module provides the following constant...
12.1.pickle— Python object serialization¶ Source code:Lib/pickle.py Thepicklemodule implements binary protocols for serializing and de-serializing a Python object structure.“Pickling”is the process whereby a Python object hierarchy is converted into a byte stream, and“unpickling”is the inverse ...
sys 模块可以让你访问解释器相关参数,比如模块搜索路径,解释器版本号等.operator模块提供了和内建操作符作用相同的函数.copy模块允许 你复制对象, Python 2.0 新加入的gc模块提供了对垃圾收集的相关控制功能. 1.2. _ _builtin_ _ 模块 这个模块包含 Python 中使用的内建函数. 一般不用手动导入这个模块; Python会帮...
