    copied!<p>I want to display a random link + its name from an RSS feed. The code I use is:</p> <pre><code>def updateFeed(url): query_args = { 'q': 'http://news.google.com/?output=rss', 'v':'1.0', 'num': '15', 'output': 'json' } qs = urllib.urlencode(query_args) loader = 'http://ajax.googleapis.com/ajax/services/feed/load' loadurl = '%s?%s' % (loader, qs) logging.info(loadurl) result = urlfetch.fetch(url=loadurl, headers={'Referer': '...'}) if result.status_code == 200: news = simplejson.loads(result.content) </code></pre> <p>I do get response data in JSON but I don't know how to randomly select an item. Can you please advice?</p> <pre><code>{u'responseData': {u'feed': {u'feedUrl': u'http://news.google.com/?output=rss', u'description': u'Google News', u'author': u'', u'title': u'Top Stories - Google News', u'link': u'http://news.google.com/news?pz=1&amp;amp;jfkl=true&amp;amp;ned=us&amp;amp;hl=en', u'entries': [{u'publishedDate': u'Tue, 02 Aug 2011 08:51:09 -0700', u'title': u'House Approved Debt Bill Faces Final Hurdle - NY1', u'author': u'', u'content': u'&lt;table border="0" cellpadding="2" cellspacing="7" style="vertical-align:top"&gt;&lt;tr&gt;&lt;td width="80" align="center" valign="top"&gt;&lt;font style="font-size:85%;font-family:arial,sans-serif"&gt;&lt;a href="http://news.google.com/news/url?sa=t&amp;amp;fd=R&amp;amp;usg=AFQjCNEyXr4E-W9lA8bsV4_Zslubxd-6_g&amp;amp;url=http://www.theglobeandmail.com/news/world/americas/little-sign-of-compromise-ahead-of-us-default-deadline/article2114420/"&gt;&lt;img src="http://nt3.ggpht.com/news/tbn/dyFy2sz6rKRlJM/6.jpg" alt="" border="1" width="80" height="80"&gt;&lt;br&gt;&lt;font size="-2"&gt;Globe and Mail&lt;/font&gt;&lt;/a&gt;&lt;/font&gt;&lt;/td&gt;&lt;td valign="top"&gt;&lt;font style="font-size:85%;font-family:arial,sans-serif"&gt;&lt;br&gt;&lt;div style="padding-top:0.8em"&gt;&lt;img alt="" height="1" width="1"&gt;&lt;/div&gt;&lt;div&gt;&lt;a </code></pre> <p>Edit: It works now almost perfect and I learn about JSON doing this:</p> <pre><code>def updateFeed(url): query_args = { 'q': 'http://news.google.com/?output=rss', 'v':'1.0', 'num': '15', 'output': 'json' } qs = urllib.urlencode(query_args) loader = 'http://ajax.googleapis.com/ajax/services/feed/load' loadurl = '%s?%s' % (loader, qs) logging.info(loadurl) result = urlfetch.fetch(url=loadurl,headers={'Referer': '...'}) if result.status_code == 200: news = simplejson.loads(result.content) """ not working, using random.randrange instead some_key = random.choice(news.keys()) something = news[some_key] """ i = random.randrange(0,10)#to do: instead of 10, it should be number of entries title = news[u'responseData'][u'feed'][u'entries'][i][u'title'] link = news[u'responseData'][u'feed'][u'entries'][i][u'link'] return mark_safe('&lt;a href="%s"&gt;%s&lt;/a&gt;' % (link, title)) </code></pre>
