How do I parse json-object using python?

Question

I am trying to parse a json object and having problems.

import json

record= '{"shirt":{"red":{"quanitity":100},"blue":{"quantity":10}},"pants":{"black":{"quantity":50}}}'
inventory = json.loads(record)
#HELP NEEDED HERE
for item in inventory:
    print item

I can figure out how to obtain the values. I can get keys. Please help.

If you can get keys, then you can certainly get the values. That example shows a nested dictionary. Loop through it, checking if the value is a dictionary before displaying it — Kneel-Before-ZOD

You no longer have a JSON object, you have a Python dictionary. Iterating over a dictionary produces its keys.

>>> for k in {'foo': 42, 'bar': None}:
...   print k
... 
foo
bar

If you want to access the values then either index the original dictionary or use one of the methods that returns something different.

>>> for k in {'foo': 42, 'bar': None}.iteritems():
...   print k
... 
('foo', 42)
('bar', None)

import json

record = '{"shirts":{"red":{"quantity":100},"blue":{"quantity":10}},"pants":{"black":{"quantity":50}}}'
inventory = json.loads(record)

for key, value in dict.items(inventory["shirts"]):
    print key, value

for key, value in dict.items(inventory["pants"]):
    print key, value
