我想知道你是否可以提供帮助。我想在python中编写一个脚本，它将在google上运行查询并输出查询结果

这应该做你想要的：
>>> import twill.commands
>>> import BeautifulSoup
>>>
>>> class browser:
... def __init__(self, url="http://www.google.com",log = None):
... self.a=twill.commands
... self.a.config("readonly_controls_writeable", 1)
... self.b = self.a.get_browser()
... self.b.set_agent_string("Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.8.1.14) Gecko/20080404 Firefox/2.0.0.14")
... self.log = log
... self.b.clear_cookies()
... self.url=url
... def googleQuery(self, query="python code"):
... self.b.go(self.url)
... #self.b.showforms()
... f = self.b.get_form("f")
... #print "form is %s" % f
... f["q"] = query
... self.b.clicked(f, "btnG")
... self.b.submit()
... pageContent = self.b.get_html()
... soup=BeautifulSoup.BeautifulSoup(pageContent)
... ths = soup.findAll(attrs={"class" : "l"})
... for a in ths:
... print a
...
>>> t=browser()
>>> t.googleQuery("twill queries")
==> at http://www.google.ie/
Note: submit is using submit button: name="btnG", value="Google Search"
