Answer to Question #239719 in Python for Addie

Question

Using functions and other program constructs write a program that records the coursework

marks for students enrolled in HCSCI132. The coursework marks consists of three practical

assignments, one theory assignment, two tests and a mini project. The program should be

able to carry out the following operations:

a) Store marks in appropriate data types or data structures and relate the marks with the

student registration number and programme.

b) Calculate the overall coursework mark using formula;

Overall coursework mark = average practical mark * 15% + average of (theory

assignment + test marks)*15% + mini project * 10%

c) Display students who got less than half of the overall coursework i.e. 20% and below.

d) Display all student overall coursework marks ranked from the highest score to the lowest
