Need a help for this error!

[wstsxaiyun]

hey,I`m a new bird,need help for this error!

when I run the main.py,there is an error:
> main.py: error: the following arguments are required: -k/--42619108b0*****8c0e6839f, -s/--3c370a57e6******29fc9f5346e1a359aa6f4c, tests

I replace --key,--secret like this:
parser = ArgumentParser(description="Run Gate APIv4 demo application")
parser.add_argument("-k", "--42619108b08c0e6839f", required=True, help="Gate APIv4 Key")
parser.add_argument("-s", "--3c370a57e6*29fc9f5346e1a359aa6f4c", required=True, help="Gate APIv4 Secret")
parser.add_argument("-u", "--url", required=False, help="API base URL used to test")
parser.add_argument("tests", nargs='+', help="tests to run")
options = parser.parse_args()

then the error happened! How shoul I replace the params!
