[Python] python3 does not recognizes json

i am collecting json strings from several logs and append it to an list. then i iterate over the items in the list. Now the problem. the listentries are json but i am unable to convert it to list to work on the key value parts, its only string. Manually echoing the string into jq gives a valid json. Taking in ipython3 (on the same machine) the string into an variable, its a list wich i want.
