How to cache a Nested Dictionary in Redis to use by applications written in Python and Java

I have a nested dictionary in the form of{"Albert Einstein":{germany:4, UnitedStates:3},"Afganistan":{afganistan:4}}

where each key isWikipedia Title and Value is another dictionary. This is in the form of Python Pickle. I want to use this dictionary in Java .

what is the best way to do? Is it a good way to load the dictionary into Redis cache in python and use this redis cache in Java application. Does Nested ditionary work in Redis cache ?

Any help is appreciated.
