Answer 1

Vishnu, i have put your code in a new file, also some comments to the issues. Thanks for helping us by linking the code here. Without this, it would not has been possible to find the issue. Be aware, that on SoloLearn Playground your json file is only available during the execution of your code. On a local system, the json file will be persistant.
