就个人而言,我写道:
# Python 2.7
import urllib
url = 'http://www.boursorama.com/includes/cours/last_transactions.phtml?symbole=1xEURUS'
sock = urllib.urlopen(url)
content = sock.read()
sock.close()
print content
Et si tu parles français,.. bonjour sur stackoverflow.com !

事实上,我现在更喜欢使用以下代码,因为它更快:
# Python 2.7
import httplib
conn = httplib.HTTPConnection(host='www.boursorama.com',timeout=30)
req = '/includes/cours/last_transactions.phtml?symbole=1xEURUS'
try:
conn.request('GET',req)
except:
print 'echec de connexion'
content = conn.getresponse().read()
print content
在此代码中更改httplib
为http.client
应该足以使其适应 Python 3。
.
我确认,通过这两个代码,我获得了我看到您感兴趣的数据的源代码:
<td class="L20" width="33%" align="center">11:57:44</td>
<td class="L20" width="33%" align="center">1.4486</td>
<td class="L20" width="33%" align="center">0</td>
</tr>
<tr>
<td width="33%" align="center">11:57:43</td>
<td width="33%" align="center">1.4486</td>
<td width="33%" align="center">0</td>
</tr>

将以下代码段添加到上述代码中将允许您提取我认为您想要的数据:
for i,line in enumerate(content.splitlines(True)):
print str(i)+' '+repr(line)
print '\n\n'
import re
regx = re.compile('\t\t\t\t\t\t<td class="(?:gras )?L20" width="33%" align="center">(\d\d:\d\d:\d\d)</td>\r\n'
'\t\t\t\t\t\t<td class="(?:gras )?L20" width="33%" align="center">([\d.]+)</td>\r\n'
'\t\t\t\t\t\t<td class="(?:gras )?L20" width="33%" align="center">(\d+)</td>\r\n')
print regx.findall(content)
结果(仅结束)

我希望您不打算在外汇上“玩”交易:这是快速赚钱的最佳方式之一。

对不起 !我忘记了您使用的是 Python 3。所以我认为您必须像这样定义正则表达式:
regx = re.compile( b '\t\t\t\t\t......)
也就是说在字符串之前加上b,否则你会得到类似这个问题的错误
