NAME
pythonw – run python script allowing GUI
SYNOPSIS
pythonw ...
DESCRIPTION
pythonw is used to run python scripts that may display a graphical user interface (GUI). Pass the same arguments to pythonw as you would to python(1). For executable scripts, use pythonw in the "#!" line.
Actually, since Python 2.5, the normal python also allows GUI access, so python and pythonw are now interchangeable.
