The last time I tried this was quite a while ago and your question was exactly why I tried. But, it failed with some unintuitive errors in dependencies of my Python script, and I gave up after 10 mins of Googling. I’m still wary of that experience and will avoid Python where I have such deployment needs unless the language natively comes up with such a build solution. FWIW, I think borg(backup solution written in Python and C) uses pyinstaller to get a single binary executable. It may be of interest to you.
