导入urllib 来自bs4进口BeautifulSoup 导入重新
sumt = 0
html = urllib.urlopen(' http://python-data.dr-chuck.net/comments_338391.html')。read()
汤= BeautifulSoup(html)
tags = soup(' span')
表示标签中的lne: lne = str(lne) data = re.findall(' [0-9] +',lne) data [0] = int(data [0]) sumt = sumt + data [0]
打印sumt
错误:
IOError: [Errno socket error] [Errno 11004] getaddrinfo failed

请注意,urllib.urlopen
已被弃用;你应该使用urllib2.urlopen
。
无论如何,对我来说两个版本都运行良好。
import urllib2
import re
if __name__ == '__main__':
url = 'http://python-data.dr-chuck.net/comments_338391.html'
comments = {}
pattern = re.compile('<tr><td>(?P<name>.+?)</td>.+?class="comments">(?P<count>\d+)</span>.+?')
for line in urllib2.urlopen(url).read().split('\n'):
m = pattern.match(line)
if m:
comments[m.group('name')] = int(m.group('count'))
print(comments)
收率:
