JSON module for Python

JSON (Java Script Object Notation): A lightweight data interaction format that is easier to read and write than XML, is easy to parse and generate, and JSON is a subset of JavaScript. The process of serializing and deserializing the JSON modules of Python is encoding and decoding, respectively.

• Encoding: Converts a Python object encoding into a JSON string.
• Decoding: Converts the JSON format string encoding into a Python object.

JSON provides four functions: Json.loads json.dumps json.load json.dump. Loads and dumps are used to handle strings, and load and dump are used to process the files.

• Loads: Converting JSON to other formats, strings or file-related
• Dumps: Convert other objects or formats to JSON format
• Load: Converts the contents of a file into JSON data
• Dump: Writing JSON data to a file

Program examples

　　1. Convert dict format to JSON string format

Import= dict (name='huangdongju', age=25,message='something  ')print  (a) print = Json.dumps (a)  Print  (b)print (type (b))

Results:

2. Convert the JSON format to a dict

c = Json.loads (b)print ( type (c)) print ( c)print (c[' name '])

Results:

3. Write the JSON to the file

" " {"A": 1, "B": 2, "C": 3} " " With open ('a.txt','w') as F:    Json.dump ( JSONDATA,F)

Results:

4. Converting from a file to a JSON format

With open ('a.txt','r') as fr:    = json.load ( FR)    print  (    m)print (Type (m))

Results:
