Hi all

I am trying to parse some data that is, as far as I can guess, in JSON format
Data is at http://www.ebi.ac.uk/pdbe/api/pdb/entry/molecules/2k8v

I am trying to do
 f = load("http://www.ebi.ac.uk/pdbe/api/pdb/entry/molecules/2k8v";)

and "print f" shows it

{"2k8v":[{
        "entity_id":1,
        "weight":17801.109,
etc

Now the question: how to extract parts of the data, like the value for the 
"weight" key?
I tried things like
print f["weight"]
print f["2k8v"]["weight"]
print f["2k8v"][0]["weight"]
print f["2k8v"][1]["weight"]

without success

Any help is appreciated
