class wx app question

i found this code snippet in one example in matplotlib

class App(wx.App):

def OnInit(self):
    'Create the main window and insert the custom frame'

    frame = CanvasFrame()

    frame.Show(True)

    return True

app = App(0)
app.MainLoop()

i just want to ask what does app = App(0) mean, why do we need 0 for an argument

It explicitly disables the redirection of sys.stdout and sys.stderr.
