As you said,
then why are you making it so complicated for just a list of lists. 
Look at the image and think → Repeating the same keys over and over, is it worth? So many blocks over here are totally redundant. More over If a single mismatched letter or a simple dot is present in any of those keys, then getting data of that key value is just gone. Just think about it.
I have no idea why did ray guided you to go with
No, it’s not for this type.
Remember this, no matter what → the dictionaries are best where the keys vary or are unique, not with the fixed items like this…
By the way…
which is gonna be very simple with the list of lists. The retrieval is also quite simple.
Coming back to your blocks, the dictionary is not properly structured. It’s the wrong method, totally.
It’s upto you, if you still want to stick with the dictionaries (unnecessary over here), then let me know. I’ll help you build the dictionaries, with a proper method.
Adding items with to the lists 
is unbelievably simple.
Heading to →
is to make a list of keys to your value path.
Your dictionary will be a comedy thing just
