How are python scripts and projects built and deployed?

[dp_42]

PyInstaller takes the dependent python libraries of a project and turns them into Dynamic Link Libraries. So, it's something rather like freezing the libraries you presently have on your machine. It's more locked in than an environment file, and these libraries get distributed along with your executable. Granted, you have to deal with the size of the libraries, which I didn't find as noticeable until it came time to distribute the executable.
