I recently used PyInstaller to wrap Black (the code formatter) and it worked perfectly in two minutes. Literally one command to take the whole script and produce a standalone executable. There's also something like this: https://build-system.fman.io/

The thing about pyInstaller is that it works absolutely perfectly... until it doesn’t. In which case you are stuck spending days on trying to kick everything in your project into shape with the hope of it working.

That is what I hate most about Python, there is only one sure-fire way of doing packaging and that’s setting it up even before you write your first line of code and the testing constantly as your project evolves.

Myself and others have absolutely no trust in the several build pathways because they all fail horrible for a wide range of reasons. To the counter, if I have a C++ or C# project I’m very confident that it will almost always be a breeze to package it up.
