Programming Forums - wxPython syntax error help.

I'm following the getting started tutorial here and when I try adding the OnOpen method I get this syntax error:

: python partTwo.py 

  File "partTwo.py", line 15

    filemenu.Append(ID_OPEN, '&Open', 'Open a file')

    ^

SyntaxError: invalid syntax

here is the full source code.

            f.close()

        dlg.Destroy()

app = wx.PySimpleApp()

frame = MainWindow(None, -1, "Sample editor")

app.MainLoop()

I'm running this on Mac OS 10.4.7 with Python 2.4.3 and wxPython 2.6.

any and all help is very much appreciated :) thank you.
