Get all keys of a nested dictionary

I have the below code which currently just prints the values of the initial dictionary. However I would like to iterate through every key of the nested dictionary to initially just print the names.

Nested dictionary comprehension python

I’m having trouble understanding nested dictionary comprehensions in Python 3. The result I’m getting from the example below outputs the correct structure without error, but only includes one of the inner key: value pairs. I haven’t found an example of a nested dictionary comprehension like this; Googling “nested dictionary comprehension python” shows legacy examples, non-nested comprehensions, or answers solved using a different approach. I may be using the wrong syntax.
