JSON & Pickle

JSON & Pickle

JSON: Typically used for serialization and deserialization between different programming languages, the core of which is the string, which is the conversion between the string and the basic data type of Python

The JSON module provides four functions:dumps, dump(serialization, Save), loads(deserialization, read), load

#json.loads is used to convert strings in dictionaries, lists, and elements into corresponding dictionaries, lists, tuples#for the contents of the dictionary, there must be ""#Example:L ="[11,22,33,44]"ImportJsonresult=json.loads (L)Print(Result,type (result))#output: [One, all, <class] ' list ' >json.dumps ()#convert Python's basic data type to stringUser_list = [11,22,33,44]Importjsons=json.dumps (user_list)Print(S,type (s))

Pickle: A basic data type that is specific to Python and a conversion between sequences that only Python can recognize, which is often the bytes type. Pickle is powerful in the ability to serialize code, class

The Pickle module provides four functions:dumps, dump(serialization, Save), loads(deserialization, read), Load
