Convert json like structure into json in python language

Question

I am calling 3rd party API which is sending response in text/html format. It is a key value pair but not exactly json.

current : { data:"true" ,results:15} expected : "data":"true" , "results":15}

I am trying to parse using json.loads to create a dictionary but as it's clear from the structure it's not exactly json and python throws the error as well.

{JSONDecodeError}Expecting property name enclosed in double quotes: line 1 column 3 (char 2)

Is there a way to fix the response and convert it into proper json or is there any other way where I can get key value pair out of the response

yaml is unable to help me in this case coz, entire data:

{ success:true ,results:9,rows:[{sym:"FEDERALBNK",ser:"EQ",Ind:"-",face:"2",sub:"Annual General Meeting And Dividend Rs.5/- Per Share",exDt:"02-Sep-2010",recordDt:"-",bcStartDt:"04-Sep-2010",bcEndDt:"13-Sep-2010",ndStartDt:"-",comp:"The Federal Bank  Limited",isin:"INE171A01011",ndEndDt:"-"},{sym:"FEDERALBNK",ser:"EQ",Ind:"-",face:"2",sub:"Annual General Meeting And Dividend Rs.8.50 Per Share",exDt:"23-Aug-2011",recordDt:"-",bcStartDt:"25-Aug-2011",bcEndDt:"03-Sep-2011",ndStartDt:"-",comp:"The Federal Bank  Limited",isin:"INE171A01011",ndEndDt:"-"},{sym:"FEDERALBNK",ser:"EQ",Ind:"-",face:"2",sub:"Annual General Meeting And Dividend Rs.9/- Per Share",exDt:"20-Jul-2012",recordDt:"-",bcStartDt:"24-Jul-2012",bcEndDt:"02-Aug-2012",ndStartDt:"-",comp:"The Federal Bank  Limited",isin:"INE171A01011",ndEndDt:"-"},{sym:"FEDERALBNK",ser:"EQ",Ind:"-",face:"2",sub:"Annual General Meeting/Dividend Rs 9/- Per Share",exDt:"09-Jul-2013",recordDt:"-",bcStartDt:"11-Jul-2013",bcEndDt:"20-Jul-2013",ndStartDt:"-",comp:"The Federal Bank  Limited",isin:"INE171A01011",ndEndDt:"-"},{sym:"FEDERALBNK",ser:"EQ",Ind:"-",face:"2",sub:"Annual General Meeting / Dividend - Rs 2/- Per Share",exDt:"04-Jul-2014",recordDt:"-",bcStartDt:"08-Jul-2014",bcEndDt:"17-Jul-2014",ndStartDt:"-",comp:"The Federal Bank  Limited",isin:"INE171A01011",ndEndDt:"-"},{sym:"FEDERALBNK",ser:"EQ",Ind:"-",face:"2",sub:"Annual General Meeting / Dividend - Rs 2.20/- Per Share",exDt:"28-May-2015",recordDt:"-",bcStartDt:"01-Jun-2015",bcEndDt:"05-Jun-2015",ndStartDt:"-",comp:"The Federal Bank  Limited",isin:"INE171A01011",ndEndDt:"-"},{sym:"FEDERALBNK",ser:"EQ",Ind:"-",face:"2",sub:" Annual General Meeting/ Dividend -Re 0.70 Per Share",exDt:"29-Jul-2016",recordDt:"-",bcStartDt:"02-Aug-2016",bcEndDt:"11-Aug-2016",ndStartDt:"-",comp:"The Federal Bank  Limited",isin:"INE171A01011",ndEndDt:"-"},{sym:"FEDERALBNK",ser:"EQ",Ind:"-",face:"2",sub:" Annual General Meeting/Dividend - Re 0.90 Per Share",exDt:"03-Jul-2017",recordDt:"-",bcStartDt:"05-Jul-2017",bcEndDt:"14-Jul-2017",ndStartDt:"-",comp:"The Federal Bank  Limited",isin:"INE171A01011",ndEndDt:"-"},{sym:"FEDERALBNK",ser:"EQ",Ind:"-",face:"2",sub:" Annual General Meeting/Dividend- Re 1 Per Share",exDt:"02-Aug-2018",recordDt:"-",bcStartDt:"04-Aug-2018",bcEndDt:"10-Aug-2018",ndStartDt:"-",comp:"The Federal Bank  Limited",isin:"INE171A01011",ndEndDt:"-"}]}

after using yaml it turns into:

which i can't access like:

yaml.load(corporate_action)['rows'][0]['sym']

Regex might help here. You can use re.sub

Ex:

import re
import json


data = '{ data:"true" ,results:15}'
data = json.loads(re.sub(r"(\w+):", r'"\1":', data))
print(data)

Output:

{u'data': u'true', u'results': 15}

I have slightly optimised your solution to suit me. re.sub(r"([a-zA-Z]+):", r'"\1":', data) (\w+) was changing colon occurring in value side as well
