'''Weight:''' 15% of the overall grade
'''Due Date:''' Ask your professor for exact date
'''Late Penalty:''' 20% per school day, and note that this assignment in an alternative to assignment 2, or an alternative to other OPS435 assessments. Same rules applied to this assignment as assignment 2
==Overview==
As most system administrators, you would like to offer email notification to your users based on the event that triggers it. In a school environment, classes may be cancelled in a daily basis and the classes being cancelled may be posted to a web site and it is up to the students to check it out. If you do not check the class cancellation web site before heading to your class, you may be disappointed when you get there and find out that your class has been cancelled. It would be nice if you can get an email send to you for any class cancellations before you leave home for the class. For this assignment, you are going to write a python script to poll data from the class cancellation web site (any given web site, but you can use the web page [https://scs.senecac.on.ca/~raymond.chan/ops435/a3/ccn.html here] for testing purpose) and send an email to any body subscribe to you email notification service ( a sample subscription web page [https://wiki.cdot.senecacollege.ca/wiki/OPS435_Python_A3_CCN_Subscription here] that their classes have been cancelled.
== Instruction ==
=== Program Name and valid command line arguments ===
Name your Python3 script as <code>ccn_[student_id].py</code>. 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>
usage: ccn.py [-h] [-s SITE] [-t {table,text}] [-n {table,text}] N [N ...]
Class Cancellation Notification System
positional arguments:
N list of notification subscription sites to be
processed.
optional arguments:
-h, --help show this help message and exit
-s SITE, --site SITE class cancellation web site
-t {table,text}, --type {table,text}
type of class concellation data: table -> html table,
text -> plain text file
-n {table,text}, --notification {table,text}
type of notification data: table -> html table, text
-> plain text file

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.
If there are more than one CCN subscription web pages provided, merge all the subscription list with the first one at the top and the last one at the bottom. Read and process the subscription list in that order in your program.
If no class cancellation site specified, default to https://scs.senecac.on.ca/~raymond.chan/ops435/a3/ccn.html.
If no -t or -n specified, default to html table.

=== Sample Output ===
You python script should check the class cancellation notification site for any classes cancellation that are going to happen in the next 24 hours. If it identifies any classes, it should check the class cancellation notification subscription sites for any matches. If there is any matches, it should send an appropriate email to all the subscribers using the following template:
<pre>
Dear <subscriber full name>,
Your <class code> scheduled on <data and time> is being cancellated. Details about the cancellation can be found and confirm at <Class Cancellation Notification site>.
Your class cancellation notification team.
Message generated on <Date and time stamp>
</pre>
The sample message should also be written to your CCN log file named ccn.log.
