Insert a list of URLs in the python file
Retrieve the list of feed found
Do a bit of cleanup to remove non feed items (remove URL with comments or derivative of opensearch.xml files)
You can then use a online tool such as this one to generate an OPML file to bulk import these feeds: https://dotriz.com/tools/opml-generator/

Warning

Feeds might be incorrect, too verbose or unrelated to infosec, I will sort the feed after import in my RSS feed reader
