How to convert python logging config to datadog grok parser rule?

Question

i have a logging config like

    logging.basicConfig(
        format='[%(asctime)s] {%(filename)s:%(lineno)d} %(levelname)s - %(message)s',
        level=logging.INFO,
        handlers=[
            logging.StreamHandler(sys.stdout)
        ]
    )

It is really difficult for me to convert it to grok rules even i read the following
