ParseResult(scheme='https', netloc='www.example.com', path='/', params='', query='keyword=abc&id=12', fragment='')

>>> url.query
'keyword=abc&id=12'

>>> parad=parse.parse_qs(url.query)
>>> parad
{'keyword': ['abc'], 'id': ['12']}

>>> para.get('id')
['12']

>>> parse.parse_qs(url.query).get('id')
['12']

[('keyword', 'abc'), ('id', '12')]
