Having some fun with the Spotify API and Python!
If you want to run my code for your own Spotify data, you will need to create an Spotify developers account and create an app to have a Client ID and Client Secrete code.
If you want to run this code with your data, you should create a secret.json file and add your credentials in the following way:
{"client_id": "your Spotify client ID here",
"client_secret": "your Spotify Secret Key here"}
