Answer 1

I had a similar issue with wanting to change the dictionary's structure (remove/add) dicts within other dicts.

For my situation I created a deepcopy of the dict. With a deepcopy of my dict, I was able to iterate through and remove keys as needed.Deepcopy - PythonDoc

A deep copy constructs a new compound object and then, recursively, inserts copies into it of the objects found in the original.

Hope this helps!
