Ok @miconda, I think I learned how to do all the Github related stuff and went with the `#if PY_VERSION_HEX >= 0x03070000` style of version checking based on https://docs.python.org/3/c-api/apiabiversion.html
While this patch "fixes" the Python3.7 deprecation warnings, I don't know how the project overall likes to handle things like this. I'm guessing that true devs would prefer to NOT litter code with `#if #endif` statements, but that's for you guys to decide.
Thank you for letting me try to contribute.
