通过urlparse提供了强大的url解析能力:

>>> url="http://localhost/test.py?a=hello&b=world "
>>> result=urlparse.urlparse(url)
>>> result
ParseResult(scheme='http', netloc='localhost', path='/test.py', params='', query='a=hello&b=world ', fragment='')
>>> urlparse.parse_qs(result.query,True)
{'a': ['hello'], 'b': ['world ']}
>>> params=urlparse.parse_qs(result.query,True)
>>> params
{'a': ['hello'], 'b': ['world ']}
>>> params['a'],params['b']
(['hello'], ['world '])

urlparse
result = urlparse.urlparse("http://item.taobao.com/item.htm?id=14952833371")
>>> result.path
'/item.htm'
>>> result.query
'id=14952833371'
>>> result.hostname
'item.taobao.com'
>>> params = urlparse.parse_qs(result.query)
>>> dict: {u'id': [u'14952833371']}
