Retrieve item deep in dict tree?

I have a big hairy data structure which is a tree of nested dicts. I have a sequence of strings which represents a path through the tree. Different leaves in the tree will be at different depths (which range from 1 to about 4 or 5 at most). I want to get the value stored at that path. Thus, if
keys = ['foo', 'bar', 'baz']
I want to retrieve tree['foo']['bar']['baz'].
Is there some idiomatic, non-cryptic way to write that as a one-liner?
I'm using Python 2.7.
