if __name__ == "__main__":
    try:
        if len(sys.argv) != 2:
            print(f'usage: {sys.argv[0]} [PORT]')
        port = int(sys.argv[1])
        serve(port)
    except Exception as e:
        print('Error:', e)

My script is just using OPs script to serve it. So it works all the same.

Hello @vwrs, if you change "localhost" --> "0.0.0.0", the webserver can run from other network clients (e.g., smartphones) 😃
