A Python Script which will be responsible for notifying announcement of the running contest on Codechef. (Here is the link of file).

One day due to not aware of no alert message of the announcement in the ongoing contest, I could not solve a problem. That's why I decided to do this.

Tell me If there is any problem to use this. This will work on every OS. Then use it in the upcoming contest.
