我有以下网址：

https://stackoverflow.com/questions/7990301?aaa=aaa
https://stackoverflow.com/questions/7990300?fr=aladdin
https://stackoverflow.com/questions/22375#6
https://stackoverflow.com/questions/22375?
https://stackoverflow.com/questions/22375#3_1

我需要网址,例如：

https://stackoverflow.com/questions/7990301
https://stackoverflow.com/questions/7990300
https://stackoverflow.com/questions/22375
https://stackoverflow.com/questions/22375
https://stackoverflow.com/questions/22375

我的尝试：

url='https://stackoverflow.com/questions/7990301?aaa=aaa'
if '?' in url:
    url=url.split('?')[0]
if '#' in url:
    url = url.split('#')[0]

我认为这是一种愚蠢的方式
