Python dictionary and JSON interop operations instance _python

JSON is a lightweight data interchange format with good support in all languages. A dictionary is a data structure of Python. Can be considered an associative array.

Sometimes we need to design a dictionary to convert to JSON serialization to a file, or read JSON from a file. A simple memo.

Dict to JSON to write to file

Copy Code code as follows:

#!/usr/bin/env python
# Coding=utf-8
Import JSON
D = {' A ': ' One ', ' Second ': 2}
Json.dump (d, open ('/tmp/result.txt ', ' W '))

Write Results

Copy Code code as follows:

Cat/tmp/result.txt
{"Second": 2, "a": "One"}

Read JSON

Copy Code code as follows:

#!/usr/bin/env python
# Coding=utf-8
Import JSON
D = json.load (open ('/tmp/result.txt ', ' r '))
Print d, type (d)

Run Results

Copy Code code as follows:

{u ' second ': 2, U ' one ': U ' one '} <type ' Dict ' >
