I am facing an issue while decoding json string using json.loads(jstring). Its
working, if i do json.dumps(eval(jstring)) before json.loads(jstring). I could
not figure out the issue. I want to avoide use of "eval" here.

But, here i have to do json.dumps(eval(jstring)) before json.loads(). How to do
