Python Programming Assignment
This assignment counts for 20% of the total marks of this module. Full marks for this
assignment can be gained from complete answers to ALL questions and submitting the
Python script .py for each questions on Blackboard system before 14:00, 20th
December 2024 (Friday).
Submission Instructions
For each of the following questions
Put your Python script file into an individual script with the file name
PS_Assgn_Q(n)_StudentID.py using the Save As option under the File menu on
the editor window.
Where `n' should be the question number (i.e. one of 1, 2, 3, 4) together with any
subpart (e.g. 3a), and `StudentID' is your 8-digit Student ID number.
At the beginning of each Python script, add a comment line to state `This is the
script for Q (n) of Assignment' where 'n' is the question number.
For each question involving a graph plot, save each graph as a .png file
PS_Assgn_Q(n)_StudentID.png using the Save option on the plot window.
All graphs must include your student number in the title of the graph.
All scripts and .png/.jpg files must be uploaded together as one submission to
Blackboard under Assessment. If multiple submissions are received only your final
submission will be marked. N.B. resubmission deletes all previous submissions so
ALL files must be re-uploaded.
Scripts submitted in any form other than a .py file will not be
marked.
Exercises
When answering the following questions use the principle of top-down design to design
your algorithm before encoding it. (You do not need to submit proof of this on this occasion
but in using it you should make your scripts both accurate and efficient, as well as saving
yourself time.) You might also find it useful to review lectures and practical examples.
Note that you should only use Python commands and built-in functions covered in lectures
and practicals to answer these exercises unless you are directed otherwise. 1. Write a Python script that can print the following actions for a matrix
