Question

I am writing code that will search twitter for key words and store them in a python dictionary:

        base_url = 'http://search.twitter.com/search.json?rpp=100&q=4sq.com/'
        query = '7bOHRP'
        url_string = base_url + query
        logging.info("url string = " + url_string)
        json_text = fetch(url_string)
        json_response = simplejson.loads(json_text.content)                                              
        result = json_response['results']
        print "Contents"
        print result

The resulting dictionary is :

Contents[{
    u 'iso_language_code': u 'en',
    u 'text': u "I'm at Cafe en Seine (40 Dawson Street, Dublin) w/ 2 others. http://4sq.com/7bOHRP",
    u 'created_at': u 'Wed, 06 Oct 2010 23:37:02 +0000',
    u 'profile_image_url': u 'http://a1.twimg.com/profile_images/573130785/twitterProfilePhoto_normal.jpg',
    u 'source': u '<a href="http://foursquare.com" rel="nofollow">foursquare</a>',
    u 'place': {
        u 'type': u 'neighborhood',
        u 'id': u '898cf727ca504e96',
        u 'full_name': u 'Mansion House B, Dublin'
    },
    u 'from_user': u 'pkerssemakers',
    u 'from_user_id': 60241195,
    u 'to_user_id': None,
    u 'geo': None,
    u 'id': 26597357992,
    u 'metadata': {
        u 'result_type': u 'recent'
    }
}]

How can I access the ‘from_user’ and what is the ‘u’ before the key and value?

Answer 1

result[0][u'from_user']

The u prefix means that it’s a unicode instead of a str.
