如何使用python从html个元素中提取信息

Question

I would like to have a python script that will extract the information from the html link elements href. Here is the example html code:

<link rel="icon" href="https://scihub.copernicus.eu/dhus/odata/v1/Products('4c33088a-08e8-4422-9f3d-ed65411889ef')/Products('Quicklook')/$value"/>
<id>4c33088a-08e8-4422-9f3d-ed65411889ef</id>

The https link in the href attribute is a download link and I would like to have python script that will automate the download. I tried data extraction with selenium and request libraries but I could not make any progress. Any chance that I can find a solution?

Thank you for your answers.

import requests

url = 'https://www.facebook.com/favicon.ico'
r = requests.get(url, allow_redirects=True)
open('facebook.ico', 'wb').write(r.content)
