This code is IronPython!
Won't work with CPython.

IronPython - Hello World

import clr
clr.AddReference('System.Windows.Forms')

from System.Windows.Forms import Application, Form, Label

form = Form(Text="Hello World Form")
label = Label(Text="Hello World!")

form.Controls.Add(label)

Application.Run(form)

IronPython uses the Windows .NET CLR (Common Language Runtime) & libraries and most of the common Python syntax. The standard CPython is written to be cross platform, and that does not include the CLR.

It wasn't a question. It was some code that displays a hello world Gui. I thought that I had put it in the right place.

Also, IronPython is relatively cross-platform and cross-browser. There's mono for linux, and the Silverlight plugin.
