Your handling isn't as problematic as #253, but splitting the logic between if and try/except (instead of just using try/except) makes me concerned.

Thank you for the feedback! I understand your concern about splitting the logic between if and try/except. I can refactor it to fully use try/except for simplicity @TimidRobot

I have since updated it
