This is an old question, but I thought I'd give an updated, more detailed answer. For those landing here now, you are almost certainly using python 2.6 or greater, so you can use the built-in json module for Python 2 (or for Python 3, since Google recently added support for Python 3 on GAE). Importing is as easy as import json. Here are some examples of how to use the json module:

import json

# parse json_string into a dict
json_string = '{"key_one": "value_one", "key_two": 1234}'
json_dict = json.loads(json_string)
# json_dict: {u'key_two': 1234, u'key_one': u'value_one'}

# generate json from a dict
json_dict = {'key': 'value', 'key_two': 1234, 'key_three': True}
json_string = json.dumps(json_dict)
# json_string: '{"key_two": 1234, "key": "value", "key_three": true}'

If you are using an older version of python, stick to @Brian M. Hunt's answer.

Again, here is the doc page for the json module for Python 2, and here it is for Python 3.
