Use Python code and explain each step. GWU has a website with the list of all the final schedules for all classes in Spring 2023: https://my.gwu.edu/mod/exam_schedules/

You will see that you have to click on each letter to see the final schedules for classes that start with that letter

For example, clicking on "A" shows you all the final times and information for Accountancy, American Studies, etc.

Write a script that will output one pandas dataframe of all of the final information for all classes as given by that webpage.

The column tiles should be the information about each (CRN, Subj, Crse, Section, Building, Room, Final Date, Instructor).

The rows should contain the information for all the classes (so one combined dataframe for everything)

Use BeautifulSoup(page.text, 'lxml')
