Python cross-language data interaction, Json,pickle (serialization).

Two modules for serialization in Python

• JSON is used to convert between "string" and "Python Basic data Types"
• Pickle for "Python-specific type" and "Python basic data type" to convert between

The JSON module provides four functions: dumps, dump, loads, load

The Pickle module provides four functions: dumps, dump, loads, load

Json.dudmp ("[11,22]", open (' Db.txt ', ' W ')) #转换成字符串再保存到该文件.

Json.load (Open (' Db.txt ', ' R ')) #打开该文件装成字符串.

Import JSON
s= "{" K1 ":" 123 "}"   #注, the characters in the dictionary must be enclosed in double quotation marks before they can be converted to JSON.
L="[11,22,33,44]"= json.loads (1) #用于将字典, list, tuple form strings into dictionaries, lists, tuples. 
st = Json.dumps (l) # Converts the list to a JSON-formatted string. 
Print (Result,type (Result))
