As of right now, as far as I can tell, Python does not validate HTTPS certificates by default. As far as I can tell this is because there is no guaranteed certificates available.

So I would like to propose that CPython adopt the Mozilla SSL certificate list and include it in core, and switch over the API's so that they verify HTTPS by default.

Ideally this would take the shape of attempting to locate the system certificate store if possible, and if that doesn't work falling back to the bundled certificates. That way the various Linux distros can easily have their copies of Python depend soley on their built in certs, but Windows, OSX, Source compiles etc will all still have a fallback value.

My preference would be actually be for the included certificates file to be used by default. This would provide a consistent experience across platforms. We could provide options to look for system cert repositories if desired.
