Is there a recursive version of the dict.get() built-in?

Question

I have a nested dictionary object and I want to be able to retrieve values of keys with an arbitrary depth. I\'m able to do this by subclassing dict:

Answer 1

There is none that I am aware of. However, you don't need to subclass dict at all, you can just write a function that takes a dictionary, args and kwargs and does the same thing:

 def recursive_get(d, *args, **kwargs):
     default = kwargs.get('default')
     cursor = d
     for a in args:
         if cursor is default: break
         cursor = recursive_get(cursor, a, default)
     return cursor 

use it like this

recursive_get(d, 'foo', 'bar')
