Create a symbolic link to your script as ccn.py (e.g. use the command ln -s ccn_rchan.py ccn.py to create the link) so that you can refer to your script as ccn.py. Your script must accept one or more "web site" as its command line parameters and other optional parameters as shown below. Your python script should produce the following usage text when run with the --help option:<pre>[rchan@centos7 a1]$ python3 ./ccn.py -husage: ccn.py [-h] [-n CCN ] F [F ...] Class Cancellation Notification  positional arguments: F list of CCN subscription web pages optional arguments: -h, --help show this help message and exit -c , --class USER Class Cancellation web site -v, --verbose tune on output verbosity Copyright 2018 - Raymond Chan </pre>Replace the last line with your own full name   If there is one CCN subscription web page provided at the command line, read the subscription list from the given web page.
