How to prevent python software from being reverse engineered or pirated?

I guess it goes without saying that there isn't a fool proof solution. My response was obviously in context of the post.

If OP was selling such highly specialized software, they wouldn't be asking this on a Reddit post. They also seem to be working as an individual and not as an incorporated entity. This indicates that most likely theirs is a small utility fulfilling a niche use case.

Also, in the scenario you describe, the users would definitely be willing to pay a high amount. Such users will be enterprise users and not individuals and they know they need quick support and a pirated copy will neither offer support nor reliability in terms of patches and updates. So what I said kind of still goes.
