When dealing with complex data structures from a database or client it's useful to have a kind of "deep get" like you have, but one that gracefully handles missing entries well. Otherwise you end up with horrors like:

a.get('foo', {}).get('bar', {}).get('baz', None)

Ideally you'd like something that also handled arrays, but Python doesn't have an easy way to index an array with a default when you go off the end.

I've often ended up coding methods to do this, but it'd be cool if there was something standard.
