Understanding Dictionaries
I'm not quite understanding where dict_items is coming from. I don't see a variable for it

The dictionary is a standard built-in type. It has its own predefined methods. When you create a dictionary and assign it to a variable, you can invoke the dict methods on the variable using the dot notation, like:
var.keys()
var.values()
var.items()
var.get()
And so on.
You can find the complete list of these methods and other features, in the documentation.

{'name': 'Nicole'}
This is a declaration of a dictionary object.
student = {'name': 'Nicole'}
This is assigning the dictionary to a variable called student. From this point, you can refer to this data using the variable name, like:
student.items()
or:
student['name']
It does not matter for Python, what is the name of your variable. As long as it does not clash with a keyword or a built-in function, so you should NOT use 'dict' as variable name.
Picking the best name is important for YOU, the programmer, and whoever else is going to read your code. Good names give a good idea about what is hiding behind the name. They almost document your code on their own.

Tibor Santa can it be anything you want or does it have to be dict or var?
