I am trying to find a way to parse a JSON string and save them into mysql. This is my json!
{\"title\": My title, \"desc\": mydesc, \"url\": http//example.com}
It's unclear from your question what you trying to achieve, but If your question is how to convert JSON to python dict and then load to the table, then that's how you can do it:
my_dict = json.loads('{"title": "foo", "dest": "bar"}')
curs.execute('INSERT INTO test (title, dest) values(%(title)s, %(dest)s)', my_dict)
