How do I compile a PyQt script (.py) to a single standalone executable file for windows (.exe) and/or linux?

I started to fiddle with PyQt, and made a "beautiful" script from the pyqt whitepaper example app (pastebin)

It works perfectly in Windows and Linux (with qt environment already installed on both).

Now my question is: Since I am trying to use Qt because it is compiled (at least pure old C++ based Qt), how can I compile some .exe file to run it on Windows, or a standalone executable for Linux.

The point is that I want the program to be compiled, because of speed and portability, instead of interpreted from source, which would require a previous setup on any machine. One of the goals, for example, is sending small gui scripts via email to coworkers who are not programmers at all.

if you want completelly create one stand alone executable, you can try PyInstaller . i feel it's better to create one stand alone executable than cx_freeze or py2exe (in my experience). and easy to use (full documentation available in the site).

It supports Python 3.6 or newer.

Pass the --onefile argument if you want to create completely standalone .exe. in example :

pyinstaller.exe --onefile --windowed app.py

After spending many weeks on this and trying all the alternatives - PyInstaller, py2exe, cx_freeze,... - I created my own library: https://build-system.fman.io/. It is based on PyInstaller but solves many of its common pain points. It also lets you create native installers on Windows, Mac and Linux.
