I had to solve a similar problem once. Since my RSS feed wasn't that big, I just created a .txt file locally, loaded it at the beginning, and wrote to it at the end. But depending on how many entries you have, this can result in performance issues.

Another thing you could do is to save only the date of the latest post in a file or in a database, and compare the dates of the entries in the feed to the date of the "oldest" file you already saw.

Could be something like:

last_date = ""
with open("date.txt", "r") as d:
    last_date = d.read()

and down below in your loop:

if item.date.text > last_date:
    continue

I hope I could help you. Contact me if you have any questions.
