Microsoft Word - a4-writeup.docx Assignment 4 SENG265 Summer 2022 1 Assignment 4 Due date: Friday, July 29, 11:59 pm Submission via Git only Programming environment For this assignment you must ensure your work executes correctly on the virtual machines (i.e., Senjhalla or its analogous environment for students with M1 MacBooks) you installed/configured as part of Assignment 0 as this is our “reference platform”. This same environment will be used by the teaching team when grading the work submitted by the SENG 265 students. Submitted assignment that don’t execute correctly on the required environment will receive a failing grade or be subject to heavy penalties. The sample code for Part 1 of this assignment is available on Brightspace as well as on the ‘a3’ folder of your git repository and you must use the git pull command to download a copy of the files. Make sure that your submitted files are inside of your a4 folder of your cloned Git repository. Hint: To verify whether you uploaded the files properly, simply clone the git repository to a new directory on your computer and check that the desired files are placed properly. Individual work This assignment is to be completed by each individual student (i.e., no group work). Naturally you will want to discuss aspects of the problem with fellow students, and such discussion is encouraged. However, sharing of code fragments is strictly forbidden. Code-similarity analysis tools are used to check submitted work for plagiarism. Learning objectives I. Learn object-oriented design with Python ― using classes, objects, and attributes (methods and data). II. Appreciate the concepts of abstraction and encapsulation III. Learn how to structure Python projects into multiple files ― packages and modules. IV. Learn Python type hinting V. Learn how to generate random numbers in Python VI. Learn how to manipulate sequential text files using functions in Python VII. Learn how to understand application programmer interfaces (APIs) VIII. Learn how to generate HTML5 and SVG code programmatically IX. Learn top-down design using function decomposition X. Appreciate how you can configure Python programs with a configuration class. XI. Continue to learn incremental development. The starting point for A4 is a complete Python program. You need to study and understand this program to complete the assignment. XII. Learn how to read and understand existing code and build upon it. XIII. Use Git to manage changes in your source code and annotate the evolution of your solution with messages provided during commits. Update your git repository after every major editing session to make sure that you don’t loose your work. Assignment 4 SENG265 Summer 2022 2 Instructions Assignment 4 consists of three (3) separate Python projects. The idea is to develop the famous SENG 265 Python Arts program incrementally. All three parts are required. The first two parts are worth 20% each and Part 3 is worth 60%. Store the three different Python projects in three subdirectories called a41, a42, a43 of the a4 directory. Part 1 The purpose of Part I is to figure out the process of writing an HTML/SVG file and viewing this file in a web browser. So in Part 1 you are to develop an object-oriented Python project that features a Circle class and generates an HTML-SVG file as depicted in Figure 1 below. Viewing this file in a web browser will render the SVG drawing depicted in Figure 2 below. Start Part 1 by downloading this sample Python program provided and modify this program as follows. Create classes for the geometric objects (i.e., Circle (provided), Rectangle) as well as a class called ProEpiloge to generate the HTML/SVG prologue and epilogue. The class names Circle, Rectangle, and ProEpilogue are required for Part 1 for automated grading. Part 1 must generate and draw circles and rectangles (e.g., at least 20). Please note that there are no random numbers required for Part 1 (i.e., you can hardwire in your code all the numbers that appear in Fig. 1 below). Figure 1: Generated HTML/SVG code Figure 2: Sample HTML/SVG page Assignment 4 SENG265 Summer 2022 3 Part 2 Part 2 generates random numbers using a class called GenRandom (cf. Table 1) for generating random art using an art range configuration class called ArtConfig (cf. Figure 3) that can be instantiated to create different art types such as the images depicted in Figure 3 below. The output of Part 2 must be a table of random numbers as depicted in Table 1 below. Please note that not all columns are required for Part 3 but are required for Part 2. Also note that the random numbers you generate will of course be different than the numbers in Table 1. However, the random numbers should be within the ranges specified in Table 2 below. The numbers should be arranged in nicely aligned (right-justified) columns. There are no requirements with respect to white space. The class names GenRandom and ArtConfig are required for Part 2 for automated grading. Table 1: Random numbers for 10 sample geometric shapes Table 2: Random numbers for 10 sample geometric shapes Assignment 4 SENG265 Summer 2022 4 Part 3 The goal of Part 3 is to integrate the classes developed for Parts 1 and 2 into a third Python project and generate some beautiful greeting cards for your friends and family in the form of HTML-SVG pages. That is, Projects 1 and 2 are test programs for the various classes required for Part 3. Instantiate three configuration class objects to generate different art types as depicted in Figure 3 below. Image titles and captions are optional. All the class names required for Parts 1 and 2 are required for Part 3. Figure 3: SENG 265 ART Assignment 4 SENG265 Summer 2022 5 Important requirements for grading  Your Python projects must execute perfectly under the Senjhalla virtual machine.  The most important grading requirements are effective object-oriented design and effective program decomposition.  You must use classes and objects for geometric objects (i.e., Circle, Rectangle), art configuration (i.e., ArtConfig) as well as HTML-SVG prologue and epilogue (i.e., ProEpilogue)  To facilitate automated grading o the following call names are required for the required classes: Circle, Rectangle, ProEpilogue, ArtConfig, and GenRandom o each class and each method must have a docstring containing the class or method name (e.g., “““Circle class””” or “““ drawCircle method”””) right below the class or function header o all three projects must have a main() function o for Projects 1 and 3, generate valid, multi-line, and indented HTML-SVG files o all three projects must use Python type hints. o all three projects must include at three useful doctests (e.g., cf. Exam C solutions) o for all three projects, global, program-scope, or file/module-scope variables must not be used. What to submit  Submit all three parts in separate directories/folders to your a4 folder of your Git repository as follows.  The three different Python projects must be stored in three subdirectories/folders called a41, a42, a43 that are in your a4 directory.  Hint: To verify whether you uploaded the files properly, simply clone the git repository to a new directory on your computer and check that the desired files have been placed properly.  Part 1: Submit your Python program (a41.py) as well as the generated HTML file (a41.html)  Part 2: Submit your Python program (a42.py) as well as a screenshot of your random table (a42.jpg)  Part 3: Submit your Python program (a43.py) as well as three screenshots of your art (a431.jpg, a432.jpg, and a433.jpg) Grading assessment  The first two parts are worth 20% each and Part 3 is worth 60%.  Straying from the assignment requirements will result in zero marks due to automated grading. Additional Criteria for Qualitative Assessment • Documentation and commenting: the purpose of documentation and commenting is to write information so that anyone other than yourself (with knowledge of coding) can review your program and quickly understand how it works. In terms of marking, documentation is not a large mark, but it will be part of the quality assessment. • Proper naming conventions: You must use proper names for functions and variables. Using random or single character variables is considered improper coding and significantly reduces code readability. Single character variables as loop variables is fine. • Debugging/Comment artifacts: You must submit a clean file with no residual commented lines of code or unintended text. • Quality of solution: marker will access the submission for logical and functional quality of the solution. Some examples that would result in a reduction of marks #!/usr/bin/env python """Assignment 4 Part 1 template""" print(__doc__) from typing import IO class Circle: """Circle class""" def __init__(self, cir: tuple, col: tuple) -> None: self.cx: int = cir[0] self.cy: int = cir[1] self.rad: int = cir[2] self.red: int = col[0] self.green: int = col[1] self.blue: int = col[2] self.op: float = col[3] def writeHTMLcomment(f: IO[str], t: int, com: str) -> None: """writeHTMLcomment method""" ts: str = " " * t f.write(f"{ts}\n") def drawCircleLine(f: IO[str], t: int, c: Circle) -> None: """drawCircle method""" ts: str = " " * t line1: str = f'' f.write(f"{ts}{line1+line2}\n") def genArt(f: IO[str], t: int) -> None: """genART method""" drawCircleLine(f, t, Circle((50,50,50),
