python nested dictionary access

Getting dictionaries back from a http endpoint usually results in a mess of objects. Dealing with this in python can be a challenge of ValueError exceptions. so what is the easiest way to handle this? a nested get. if the object looks like

message={"detail":{"operation":"create"}}

then you can access it like this

message.get('detail', {}).get('operation')

then if you access something that doesn’t exist you will get a nice None back

>>> print(message.get('detail', {}).get('notoperation'))
None

hurray safe handling of missing values
