Calculate Your Class Grade

---

Updated the code to sort of automate the process a bit more. You will need to have BeautifulSoup installed to use. What you have to do is navigate to the page with your grades for each section and then you have to save the page to your computer.

• Firefox: Save Page > Web Page, complete
• Chrome: Save page as... > Webpage, Complete

Naming convention

If you name your files as follow, the script will automatically load them for you:

• Assignments: assignments.html
• Exam: exam.html
• Quizzes: quiz.html

Results

If you've saved the pages together in the same folder, you then simply have to run the script from that folder. If you did not name the files as I specified or you are running the script from some other location, you will be prompted to provide the file names.

====================

====================
     Quizzes: 100.0
 Assignments: 150.0
  Final Exam: 20.0
--------------------
 Total Grade: 270.0

You passed with distinction!

Disclaimer

I was fortunate enough not to have to take the quizzes or the assignments more than once, so I'm not sure how that will affect the outcome of your results. This is also the very first time that I attempt to use BeautifulSoup, so if it seems hacky it's because it is :)
