我遇到了以下问题:

使用Twitter API和tweepy模块,我想监控趋势主题并从数据中提取主题标签.

这段代码:

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import tweepy, json

CONSUMER_KEY = 'key'
CONSUMER_SECRET = 'secret'
ACCESS_KEY = 'key'
ACCESS_SECRET = 'secret'
auth = tweepy.OAuthHandler(CONSUMER_KEY, CONSUMER_SECRET)
auth.set_access_token(ACCESS_KEY, ACCESS_SECRET)
api = tweepy.API(auth)

trends1 = api.trends_place(1)
print trends1

给我关于全局趋势主题的数据,结构如下:

[{u'created_at': u'2014-04-16T12:13:15Z', u'trends': [{u'url': u'http://twitter.com/search?q=%22South+Korea%22', u'query': u'%22South+Korea%22', u'name': u'South Korea', u'promoted_content': None}, {u'url': u'http://twitter.com/search?q=%23FETUSONEDIRECTIONDAY', u'query': u'%23FETUSONEDIRECTIONDAY', u'name': u'#FETUSONEDIRECTIONDAY', u'promoted_content': None}, {u'url': u'http://twitter.com/search?q=%23PrayForSouthKorea', u'query': u'%23PrayForSouthKorea', u'name': u'#PrayForSouthKorea', u'promoted_content': None}, {u'url': u'http://twitter.com/search?q=%23GaraGaraRP', u'query': u'%23GaraGaraRP', u'name': u'#GaraGaraRP', u'promoted_content': None}, {u'url': u'http://twitter.com/search?q=%23%D8%A5%D8%B3%D9%85_%D8%A3%D9%85%D9%8A_%D8%A8%D8%AC%D9%88%D8%A7%D9%84%D9%8A', u'query': …

我正在使用此代码计算文本文件中单词出现的频率:

#!/usr/bin/python
file=open("out1.txt","r+")
wordcount={}
for word in file.read().split():
    if word not in wordcount:
        wordcount[word] = 1
    else:
        wordcount[word] += 1
for k,v in wordcount.items():
    print k, v

如何按频率编号的降序打印输出？
