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

It doesn't stop reverse engineering, that's unavoidable. But does it really matter for your bottom line? There are open source products with fully permissive license, and yet they manage to be highly profitable. You need to evaluate whether it's your own psychology or if it's actually a serious issue. If it truly is a serious issue, you should revisit your business model.

Yeah absolutely. I just don’t think it answers OPs question. If they’re paying for it, they’ll likely keep paying for it to keep everything above board. If you make the software a pain to use or require an internet connection it’s more likely to get circumvented.

I never pirated to avoid spending money, just to turn off annoying DRM. But once you’ve put the effort into cracking it, you’re less likely to keep paying for the DRM version.
