Heya Peter. I'd look into if you asked nicely but I'm not going to waste my time. I'd recommend checking into your launchpad settings to change your subscriptions.

    Handle StopIteration for Py3.7 PEP 0479

    Replace raise of StopIteration with return.

    PEP 0479, https://www.python.org/dev/peps/pep-0479/, makes the
    following change: "when StopIteration is raised inside a generator,
    it is replaced it with RuntimeError".
    And states: "If raise StopIteration occurs directly in a generator,
    simply replace it with return."
