Python Variables: Homework Notbook`

Use this Notbook to perform Python Variable Homework Hacks.

Add-Dictionary Homework Instructions:
- Add multi-line comment to describe purpose of primitive types, replace existing single line comment
- Add multi-line comment to describe purpose of dictionary type, replace existing single line comment 
- Add dictionary inside the user_profile dictionary, a favorites dictionary as dictionary in user_profile 
- Print the user_profile.favorites dictionary

Add-Behavior Homework Instructions:
- Comment the code for class
- Comment the code for objects and dot notation usage
- Add new tracking item, for instance the favorites dictionary created in Add-Dictionary Homework
- Add behavior using the method to the class that uses the new tracking item
