JSON parsing from an API and do something with it

Using the Twitter API as an example. More particularly, we are fetching the most recent tweets containing the #cheese hashtag. See the API doc for more information.

import urllib2, json

url = 'http://search.twitter.com/search.json?q=%23cheese'
f = urllib2.urlopen(url)
data = json.load(f)

for r in data['results']:
    print r['from_user'] + ' says "' + r['text'] + '"'
