Python Programming Blueprints

Creating the DataManager class

We have implemented the base functionality to authenticate and consume data from the Spotify REST API, but now we need to create a class that will make use of this functionality so we get the information that we need to be displayed in the client.

• List the artist's albums
• List the album's tracks
• Request a track to be played
