python废料数据美国政府

Question

我收到以下错误

'IOError：[Errno套接字错误] [Errno -2]名称或服务未知'

当我尝试废弃数据时：

http://1usagov.measuredvoice.com/2013/

任何想法可能是什么原因？

这是我的代码：

import urllib
import re

import time

data = urllib.urlopen('http://1usagov.measuredvoice.com/2013/').read()
# print data
print data
# datafiles name pattern - usagov_bitly_data2011-07-29-1311919454
p = re.compile('usagov_bitly_data\d{4}-\d{2}-\d{2}-\d{10}')
# print p.findall('<tr><td valign="top"><img src="/icons/unknown.gif" alt="[   ]"></td><td><a href="usagov_bitly_data2011-07-29-1311919454">usagov_bitly_data2011-07-29-1311919454</a></td><td align="right">29-Jul-2011 07:04  </td><td')

m = p.findall(data)

# print m

for i in range(len(m)):
    if (i % 2 == 0):
        print m[i]

# time.strftime("%a, %d %b %Y %H:%M:%S +0000", time.localtime(epoch))

print len(m)

for i in range(len(m)):
    if (i % 2 == 0):
        print "downloading ", m[i]
        clicks = urllib.urlopen('http://bitly.measuredvoice.com/bitly_archive/' + m[i]).read()
        file = open(m[i], "w")
        file.write(clicks)
        file.close()
        print "done"
