Python/Json:Expecting property name enclosed in double quotes

This:

{    'http://example.org/about': {        'http://purl.org/dc/terms/title': [            {'type': 'literal', 'value': "Anna's Homepage"}        ]     }}

is not JSON.
This:

{     "http://example.org/about": {         "http://purl.org/dc/terms/title": [             {"type": "literal", "value": "Anna's Homepage"}          ]      }}

is JSON.

EDIT:
Some commenters suggested that the above is not enough.
JSON specification - RFC7159 states that a string begins and ends with quotation mark. That is ".
Single quoute ' has no semantic meaning in JSON and is allowed only inside a string.

as JSON only allows enclosing strings with double quotes you can manipulate the string like this:

str = str.replace("\'", "\"")

if your JSON holds escaped single-quotes (\') then you should use the more precise following code:

import rep = re.compile('(?<!\\\\)\'')str = p.sub('\"', str)

This will replace all occurrences of single quote with double quote in the JSON string str and in the latter case will not replace escaped single-quotes.

You can also use js-beautify which is less strict:

$ pip install jsbeautifier$ js-beautify file.js

In my case, double quotes was not a problem.

Last comma gave me same error message.

{'a':{'b':c,}}           ^

To remove this comma, I wrote some simple code.

import jsonwith open('a.json','r') as f:    s = f.read()    s = s.replace('\t','')    s = s.replace('\n','')    s = s.replace(',}','}')    s = s.replace(',]',']')    data = json.loads(s)

And this worked for me.
