Thanks for the quick response Emile! However, this only seems to solve part
of the problem. It seems to set up a single key value dictionary (e.g.
{'server1' : ['state=active', 'ncpu=8']}, etc.)I'm looking for more of a
multi-way dictionary to be able to access down different paths such as:

mymem = node['server1']['mem']
myncpu = node['server1']['ncpu']

I want to be able to change the list part of the example you provided into a
sub-dictionary similar to (preferably done directly from the original data):

{ 'server1' : { 'state' : 'active', 'ncpu' : 8}, 'server2' : {'state' :
'active', 'ncpu' : 32}}
