Hi Ana,
This is something that the development team are best placed to answer, and I'm sure that they'd be happy to know if there are bumps in the road coming up with Catalina.
I am copying this reply to the core developer list to alert them. It would be helpful if you could make as full a report as possible via
bugs.python.org. A reply-all to this email can be used to let the development team know the report reference should you do so, and the bug tracker is a better medium for such focused communication than the list.
I've moved the webmaster address to Bcc to relieve it of further traffic. Good luck!
