More Classes and OOP in Python

Use your knowledge of Python Classes to create a homework tracker!

Create your classes in the provided classroom.py file.

Exercise: Write the following classes

Let's practice writing classes with useful functionalities

• Create an Assignment class

  • Assignments have name, github_url, completed, and grade properties
  • completed's initial value should be set to False
  • grade's initial value should be set to None
  • Assignments have a mark_done method that take in the grade as an argument, and sets grade and completed

• Create a Student class

  • Students have name, pending_homeworks and completed_homeworks properties
  • Students have a assign_homework method
  • Students have a complete_homework method
  • Students have a print_outstanding_homeworks method
  • The assign_homework method takes in an Assignment object, and adds it to its pending_assignments list
  • The complete_homework method takes in the name of the homework, and the grade as an argument. It finds the specified homework in the pending_homeworks list and calls it's mark_done method. The method removes the Assignment from pending_homeworks and adds it to completed_homeworks
    • Returns True if assignment was found and modified, False if not found
  • print_outstanding_homeworks prints out the name of each of the pending_homeworks

• Create a SeiClass class

  • SeiClass has name, and students properties
  • SeiClass has an add_student method that takes in a Student object
  • SeiClass has an assign_homework method that takes in an Assignment object and assigns that assignment to every student
  • BONUS - What would need to be changed in our classes to facilitate a print_avg_grade function? Implement it!

Sample Input:

henry = Student('Henry')
sarah = Student('Sarah')
mike = Student('Mike')

sei26 = SeiClass('sei26')
sei26.add_student(henry)
sei26.add_student(sarah)
sei26.add_student(mike)

assignment1 = Assignment('Bounty Hunters', 'https://github.com/WDI-SEA/mongoose-practice')

sei26.assign_homework(assignment1)

henry.complete_homework('Bounty Hunters', 98)
sarah.complete_homework('Bounty Hunters', 95)

henry.print_outstanding_homeworks()
sarah.print_outstanding_homeworks()
mike.print_outstanding_homeworks()

Sample Output

Henry has no outstanding homeworks!
Sarah has no outstanding homeworks!
Mike still needs to turn in: Bounty Hunters
