我正在尝试使用 geograpy ( https://pypi.python.org/pypi/geograpy/0.3.7 )从文本文件中提取国家/城市名称，但它返回一个空列表。我的代码是：

import geograpy
text = 'I am from Delhi'
places = geograpy.get_place_context(text=text)

print places.cities

输出：

[]

为什么不提取城市名称？有什么办法可以解决吗？？

如何在python中对元素元组进行排序,首先是基于值,然后是基于键.考虑我将用户输入作为字符串的程序.我想找出每个字符的数量,并在字符串中打印3个最常见的字符.

#input string
strr=list(raw_input())
count=dict()

#store the count of each character in dictionary
for i in range(len(strr)):
count[strr[i]]=count.get(strr[i],0)+1

#hence we can't perform sorting on dict so convert it into tuple 
temp=list()
t=count.items()

for (k,v) in t:
    temp.append((v,k))

temp.sort(reverse=True)

 #print 3 most common element
for (v,k) in temp[:3]:
         print k,v

给予i/p -aabbbccde

上述代码的输出是:

3 b
2 c
2 a

但我希望输出为:

3 b
2 a
2 c

我希望在Twitter(https://twitter.com/HousingWire)上收到HousingWire的每条推文.我知道如何验证Twitter帐户,但我如何获得HousingWire的推文？

我知道如何根据关键字流式传输数据,但我想流式传输HousingWire推文.我怎么能这样做？
