Unable to run Simple Example

[DJ Webre]

Hi

Just installed Python2.2 and wxPython.  My OS is Win NT v4.

I was able to run several demos and samples but when I tried to run the
following, it would not run.

______________________________________
   from wxPython.wx    import *

class MyApp(wxApp):
    def OnInit(self):
        frame = wxFrame(NULL, -1, "Hello World")
        frame.Show(true)
        self.SetTopWindow(frame)
        return true

    app = MyApp(0)
    app.MainLoop()
______________________________________________

I save the above as a .py file and ran it by
Start   Program  IDLE(Python GUI)
Open the file and "ran script".
Obtainted the following:

    app = MyApp(0)
NameError: name 'MyApp' is not defined
