Question

我（主要是尝试学习python和json，但也）试图定期从twitter中提取和格式化一系列热门话题。我拼凑了很多不同的教程。它符合我的目的 - 打印我需要stdout的HTML，但我想知道我是否可以不同地考虑对象或更好地构造它。协助？

class trend:
        #these are the fields that Twitter provides, so they make up one trend.
        def __init__(self, query, name, promoted_content, events, url):
                self.query = query
                self.name = name
                self.promoted_content = promoted_content
                self.events = events
                self.url = url 

        def listitem(self):
                print "\t <li><a href=\"%s\">%s</a></li>\n" %(self.url, self.name)

class trending:
        def __init__(self,api_url,title):
                self.api_url = api_url
                self.title = title

        def get_trending(self):
                import simplejson as json
                import urllib2

                trends_all = json.loads(urllib2.urlopen(self.api_url).read())
                # test print
                # print trends_all[0]['trends']
                print "<p>%s</p> \n <ol>" % self.title

                #I'm initializing an array, though I don't actually use it. That's next.
                trends = []
                for x in trends_all[0]['trends']:
                    thistrend = trend(x['query'], x['name'], x['promoted_content'], x['events'], x['url'])
                    thistrend.listitem()
                    trends.append(thistrend) 
                print "</ol>\n"
                return trends

usa = trending("http://api.twitter.com/1/trends/23424977.json","Trending nationally")
usa.get_trending()

在你的例子中，我不明白为什么趋势需要成为一个clas，因为它只有一个函数。这可以用get_trending作为独立函数编写，它将api_url和title作为参数。

我该如何重新考虑对象/对象方向？
