I have been struggling with a python problem for several weeks. Recently I started a bounty on my question I had submitted. No one has answered yet but I have figured out the solution. May I answer my own bountied question?
Bounty is designed to attract attention. You can choose to award it to anyone else or let the system award it if the criteria are met for half awarding.
You always can and should self answer, bounty or not. Thanks so much for asking a great question and then promoting it.
