stupid q-n (wxPy)

[xam]

I am trying to run some wxPy samples and I am getting an error here:
if __name__ == '__main__':
    import sys,os
    import run
    run.main(['', os.path.basename(sys.argv[0])])

- "import run" fails. I know this is something really stupid, but I could
not find the answer on the net.
thanks.
