@amjd, thanks for sharing. I upgraded it from Python 2 to Python 3, but when I ran it, I got a 404 error on the `saved` endpoint. Does it work for you?

Edit: I see from the other PR it's called `upvoted`.

Edit 2: I changed it to `upvoted` and now I get a 200 OK, but the code crashed right afterwards on `tree.cssselect()`.
