sys.executable -- "A string giving the name of the executable binary for the Python interpreter, on systems where this makes sense."

On my mac it says `/System/Library/Frameworks/Python.framework/Versions/2.5/Resources/Python.app/Contents/MacOS/Python` (which does make perfect sense) whether I run python or pythonw. – Alex Martelli Oct 23 '09 at 05:44

The Mac doesn't need Pythonw anymore (since 2.3). Pythonw is only interesting for windows developers anymore. – Georg Schölly Oct 23 '09 at 05:50
I don't think that is true about Macs. I have some issues that are only resolved by using pythonw. – Christopher Barber Jan 21 '21 at 21:57
This does not work on Mac becasue pythonw sets the environment variable PYTHONEXECUTABLE to point to the regular python script. – Christopher Barber Jan 21 '21 at 22:05
