如何使用python解析json-object？

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

我试图解析一个json对象并遇到问题。

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.

我可以弄清楚如何获取这些值。我可以得到钥匙。请帮忙。

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

您不再拥有JSON对象，而是拥有Python字典。迭代字典产生其键。

>>> 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.

如果要访问这些值，则索引原始字典或使用返回不同内容的方法之一。

>>> 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
