Homework 4

Due: Sunday, April 12, 2020, 11:55pm

Guidelines:

All homeworks will be submitted via Courseworks. For a given assignment, all files should be put in a folder called uni-hw4, all lowercase, which is then zipped and submitted on courseworks. The folder should contain a single readme.txt which has your name, uni, the homework number, and a brief summary of your work for each part (if necessary).

OOP:

For this part, we will be modeling some objects. We will model a class, consisting of a teacher, students, and assignments. We will generate and enroll some students. Then we will generate some assignments. For each assignment, we calculate the student’s grade, pay the teacher, and assign them the grade.

Here is an example test run (from the file test.py)

 

t = Teacher('Joe')

c = Class(t)

c.register(Student('Jack', 50))

c.register(Student('Jill', 60))

c.register(Student('Jane', 75))

c.assign(Assignment(50))

c.assign(Assignment(75))

c.assign(Assignment(80))

c.assign(Assignment(90))

We can also run an interactive version utilizing the same code (%run -m engi1006_simulator)

Plot? (y/n)y

Some skeleton code will be provided. It is missing a number of methods, which you will need to implement to get this library working. This assignment is mostly an exercise in getting comfortable with an object-oriented codebase, and reading and interpreting error messages to fill in the missing details.
