有没有一种方法可以进入这些链接，在浏览器中使用氦（或硒）打开它们，然后下载成绩单，而无需手动复制和粘贴它们作为变量，然后将它们放入列表中？示例 您的URL列表：
fin = ['https://www.youtube.com/watch?v=eHnXgh0j500', None,
'https://www.youtube.com/watch?v=wDHtXXApfbc',
'https://www.youtube.com/watch?v=CJhOGDU636k'
]
for url in fin:
if url: #check for the NONE values
#do something in selenium e.g. driver.get(url)
print(url) #or just print
谢谢你的回复。我尝试了它，但它返回了以下错误：
