I wrote the below code

    import tempfile
    import atexit
    def unlink(path):
        try:
            os.unlink(path)
        except:
            pass
    parser = Configuration(use_ordered_sections=True)
    parser.read(file_or_url)
    (fd, path) = tempfile.mkstemp(suffix='.cfg')
    atexit.register(unlink, path)
    parser.write(os.fdopen(fd, 'w'))
    return path
