python url参数转dict

from urllib import parse
url='_from=R40&LH_BIN=1&_sop=13&LH_Complete=1&LH_Sold=1&_udlo=24&_udhi=48&_ipg=200&_pgn=1&_skc=0'
res = dict(parse.parse_qsl(url))

print(res)

或：
res={k.split('=')[0]: k.split('=')[1] for k in url.split('&')}

或：
res=dict(k.split('=') for k in url.split('&'))

>>>
{'_from': 'R40', 'LH_BIN': '', '_sop': '', 'LH_Complete': '', 'LH_Sold': '', '_udlo': '', '_udhi': '', '_ipg': '', '_pgn': '', '_skc': ''}

反过来：
res={'_from': 'R40', 'LH_BIN': '', '_sop': '', 'LH_Complete': '', 'LH_Sold': '', '_udlo': '', '_udhi': '', '_ipg': '', '_pgn': '', '_skc': ''}
parameters = parse.urlencode(res)
print(parameters)
>>>
_from=R40&LH_BIN=1&_sop=13&LH_Complete=1&LH_Sold=1&_udlo=24&_udhi=48&_ipg=200&_pgn=1&_skc=0
