JSON syntax is not Python syntax. JSON requires double quotes for its strings.

ANSWER 2

Score 210

you can use ast.literal_eval()

>>> import ast
>>> s = "{'username':'dfdsfdsf'}"
>>> ast.literal_eval(s)
{'username': 'dfdsfdsf'}

You can dump JSON with double quote by:

import json

# mixing single and double quotes
data = {'jsonKey': 'jsonValue',"title": "hello world"}

# get string with all double quotes
json_string = json.dumps(data)

demjson is also a good package to solve the problem of bad json syntax:

pip install demjson

Usage:

from demjson import decode
bad_json = "{'username':'dfdsfdsf'}"
python_dict = decode(bad_json)

Edit:

demjson.decode is a great tool for damaged json, but when you are dealing with big amourt of json data ast.literal_eval is a better match and much faster.
