Iris - 2025
OVERVIEW
Inspired by a high school student I met in a high-school elite event organized by SSE in 2024. Her name
is Iris. In this assignment, you are going to design and develop a program to display as many polygon
shapes as possible on the canvas in random locations within a given period of time. Your program will
load the custom shapes (name and coordinates) of all the polygons from an external file, start tracking
the elapsed time and then repeatedly perform the shape-placement operation. Initially the canvas is
empty. The shape-placement operation picks a random polygon shape, a random color and a random
pair of x, y coordinates, trying to position the chosen polygon on the canvas at the chosen x, y
coordinate, on condition that it is completely separate from all other polygons already drawn on the
canvas. If it fails, your program repeatedly attempts to place the same polygon in another location by
choosing another random pair of x, y coordinates. No polygon can be placed within another polygon
and any polygon cannot touch or overlap any other polygons. The placement operation ceases any
further attempts for another polygon once the elapsed time has expired. The duration length is defined
by the user at the program's launch. Please refer to the scope for detailed requirements.

SCOPE
1. Drawing Canvas - Use module “turtle” to create the drawing canvas, 75% width and 75% height
of computer’s screen resolution, positioned at the center of the computer’s screen.
2. Input - prompt the user to enter the following information:
a. Stretch Value - a value used to resize polygon in both width and height. Default is 1.
b. Duration - total number of seconds to place random polygons on canvas. Default is 5.
c. Random Seed - the seed value used to initialize the random module. Default is 1.
d. Terminate - ‘y’ or ’n’. Default is ’n’
3. Termination
a. after the duration is up, the program stops placing additional polygons on the canvas
and then shows the total count of polygons successfully displayed on the canvas. In the
title bar of the canvas, show your student ID, the time the operation started and ended,
elapsed time (seconds) and the number of polygons displayed:
and simply print the polygon count with your student ID on the console:
b. Change the background color of the canvas to black.
c. if “Terminate” is ‘y’ then exit the program immediately; otherwise do nothing and keep
the canvas active so that TA can verify the positions of polygons on the canvas.
4. Custom Shapes - the names and coordinates of all polygons are given in an external file called
shapes.txt. Ensure the mode of the screen is set to “logo” and register the custom shapes using
addshape(name, coordinates).
5. Shape-Placement Operation
a. Track the elapsed time
b. Pick a random color - from a predefined list of colors (see template file).

c. Pick a random polygon shape
d. Stretch the chosen polygon in both x and y directions and set the shape color
accordingly using the following methods:
i. shapesize(value, value)
ii. color(value)
e. Try repeatedly placing the chosen polygon on the canvas at a random location:
i. pick a random x, y coordinates
ii. show the polygon at the chosen x, y coordinates if the following conditions are
met:
1. no further adjustment is allowed to the polygon including rotation,
heading adjustment, shearing, etc.
2. simply call goto(x, y) to move the chosen polygon
3. the polygon must be completely separate from all other polygons
already drawn on the canvas
4. the polygon cannot be placed within another polygon
5. the polygon cannot touch or overlap any other polygons
iii. if the condition isn’t met and there is more time to continue, repeat the above
steps.
f. track of the number of polygons successfully shown on the canvas.
g. Repeat all the steps above until the total elapsed time (in seconds) exceeds the entered
duration.
6. Template File - follow the provided template file to complete the assignment.
NOTE:
• Keep your entire source code in ONE SINGLE file.
• Use only Python modules as specified in the “Permitted Modules” section.
• In your design stick ONLY to functions, in other words, no class objects of your own.
o Furthermore, the lines of code containing the sub-function(s) defined within another
function will be counted as part of the parent function.
o NOTE: Failure to adhere to the instructions outlined in the assignment handout will
result in a 50% reduction in the coding style score.

STARTUP OPTIONS
Not applicable
SKILLS
In this assignment, you will be trained on the use of the followings:
• Refactoring - logic reuse or simplification based on the existing logic.
• Variable scope: global, local and function parameters.
• Coding Styles (naming convention, meaningful names, comments, doc_string, …etc)
• Problem Decomposition, Clean Code, Top-Down Design
• Functions (with parameters and return) for program structure and logic decomposition
• Standard objects (strings, numbers & lists)
• Variable Scope
PERMITTED MODULES
Only the following Python module(s) is allowed to be used:
• turtle
• random
• time
DELIVERABLES
Program source code (A2_School_StudentID.py), where School is SSE, SDS, SME, HSS, FE, LHS, MED and
StudentID is your 9-digit student ID.
For instance, a student from SME with student ID “119010001” will name the Python file as follows:
• A2_SME_119010001.py:
Ensure that your source file is saved in standard, regular UTF-8 encoding format. On the status bar of
Visual Studio Code, you can view the current encoding format as follows:
On an occasion, the encoding scheme is set to UTF-8 with BOM as follows:
CSC1002 – 2025 Winter By Kinley Lam
CSC1002 – Computational Laboratory
The presence of the Byte Order Mark (BOM) could be due to copying from websites, older versions of
editor, file conversion from other sources, default encoding settings, and so on.
Confirm the encoding scheme is UTF-8 and the file name is correct, then submit the plain program file to
the corresponding assignment folder. A deduction of 5% will be penalized if the file is incorrectly named
or in wrong encoding format.
TIPS & HINTS
• Apply problem decomposition, Clean Code and Refactoring as illustrated during classes.
• Beware of variable scope as you might keep a few variables as global such as current editor
content, cursor position, undo buffer, and so on.
• Refer to Python website for program styles and naming conventions (PEP 8)

MARKING CRITERIA
• Coding Styles – overall program structure including layout, comments, white spaces, naming
convention, variables, indentation, functions with appropriate parameters and return.
• Program Correctness – whether or the program works 100% as per Scope.
• User Interaction – how informative and accurate information is exchanged between your
program and the player.
• Readability counts – programs that are well structured and easy to follow using functions to
break down complex problems into smaller cleaner generalized functions are preferred over a
function embracing a complex logic with many nested conditions and branches! In other words,
a design with a clean architecture and high readability is the predilection for the course
objectives over efficiency. The logic in each function should be kept simple and short, and it
should be designed to perform a single task and be generalized with parameters as needed.
• KISS approach – Keep It Simple and Straightforward.
• Balance approach – you are not required to come up with a very optimized solution. However,
take a balance between readability and efficiency with good use of program constructs.
