Just a quick and dirty sample that should help identify how the feedparser module can be used to fetch articles from RSS feeds.

feedparser_example.py

#!/usr/bin/env python3

""""""""" Import Modules """""""""
import feedparser

""""""""" Create a List of RSS feed URLs with articles to fetch """""""""
rss_feed_urls = ["https://www.us-cert.gov/ncas/alerts.xml",
                 "",
                 ]
""""""""" Walk through your list of rss feed urls """""""""
for rss_feed_url in rss_feed_urls:                      # For each URL in the list of RSS URLs...
    if rss_feed_url not in [[], "", [""], False]:       # Make sure that the url isn't empty...
        news_feed = feedparser.parse(rss_feed_url)      # use feedparser to fetch the RSS content and return it as a dictionary object...
        for article in news_feed.entries:               # For each "entry" (article) (dict object within the larger dict)....
            for key in article.keys():                  # For every key in the entry/article's dictionary...
                print(f'article["{key}"] = {article[key]}\n')   # Print the article's key and matching value.
            print("-" * 50)                             # (Just for easier visual separation)
