I am not able to parse this in python.. Please help! It is picked from Javascript it was like var A =

You can use jsonlint.com to validate JSON and see where the issues are. — Atif

What you have is not JSON.

In JSON all strings must be surrounded by double-quotes. This is an example of a valid JSON object:

{
    "common": {
        "rq": {
            "ct": ""
        },
        "up": "chg",
        "down": "chr",
        "linktargetInternal": ""
    }
}

You used regular expressions? I think it must be easier i you just open a chrome/firefox console and write: "JSON.stringify(myJSobject)"

The task needed it... I need to store the data in MySQL DB via Python.. I couldn't think of any other technique.. You could suggest anything?
