Using Session Attributes in an Alexa Skill

In this lab, you will store session attributes on the launch request to be used in the final response. Objectives for this lab include creating and setting session attributes, getting session attributes in a later intent, using the session attributes in the response, and deploying and testing the skill. **Note:** You must have your own Amazon Developer account, which you can [sign up]( for if you do not already have one.
