What is the easiest way to create a python list from a string that is in JSON format

Question

I have a string

s = '[ 1 , 2 , 3]'

how to create a list from s?

Searching for [json](https://docs.python.org/3/library/json.html) in the documentation wasn't easy enough? — Yann Vernier, Oct 21 '16 at 10:01
@kezzos **please** avoid suggesting such a solution. Thanks. — bruno desthuilliers, Oct 21 '16 at 10:07
Thanks all. I have read the doc link from @Yann Vernier. This is what I was looking for. s = '[1,3,4]' j = json.JSONDecoder() l =j.decode(s) — palazzo train, Oct 21 '16 at 10:10
The answer in http://stackoverflow.com/questions/4528099/convert-string-to-json-using-python is not the answer of this question. I just find that the correct answer should be json.JSONDecoder().decode( '[1,2,3]' ). But I cannot click the answer now. — palazzo train, Oct 21 '16 at 10:14
@PadraicCunningham, my bad, json.loads does actually work. I thought you always need the field name in the string for loads function. — palazzo train, Oct 22 '16 at 14:46

You can use the json module:

import json
s = '[1, 2, 3]'
json_as_list = json.loads(s)
