网友答案:

You don't "select" things with urllib2, because it doesn't have anything to do with a browser. Instead you need to construct the data that would be sent by the form, and post it directly:

import urllib, urllib2
data = urllib.urlencode({'2': '22'}) # assume you want to select the value "22"
request = urllib2.Request(my_url, data)
result = urllib2.urlopen(request)
print result.read()

If there are other fields, you can add them inside the dictionary that you pass to urlencode.
