Feb 13, 2016 · Python is a lovely language for data processing, but it can get a little verbose when dealing with large nested dictionaries. Let’s say you’re using some parsed JSON, for example from the Wikidata API.  The structure is pretty predictable, but not at all times: some of the keys in the dictionary might not be available all the time.
