A2. Design and write program solutions to identified problems using accepted design constructs.

Assessment Details
Part one – Caesar Ciphers1

In this part you are to develop a Python application that will encrypt text from a file and also, given the key, decrypt text from a file. We shall use an easy cipher.

Shift ciphers, also known as Caesar ciphers, are obtained as follows:

In the encryption mode, your application should ask the user for a filename which contains the plain text and the key to use for encryption. The decryption process is similar, but this time, the filename contains the encrypted text and when we give the key your application should return the original text (the arrows, shown above, go the other way).

Ideally your application should be able to handle single words, sentences, paragraphs and even whole books2 .

You need to demonstrate your application and show that it is working correctly by using tests that you design.

Part two – Your Name in Turtle Graphics
Turtle graphics is built into the Python language and there are many resources freely available3 Here are some sample images:

The requirement here is that you use the Turtle graphics to write your name – the name that appears on your student ID card. (If you have any queries ask your lecturer/tutor.)

Although you must use Python 3 in this assignment, you have creative licence in doing this application – if you are unsure, please ask your lecturer/tutor.

As an example, something like this:

It is suggested that you develop your code starting from pseudo-code and then incrementally make it better. You are also asked to keep a journal; it is useful in confirming ownership of your work and, in case you don’t reach your final goal it demonstrates your journey. The journal can consist of hand-written notes, diagrams, drawings, code-fragments, screen-shots and so on – put your journal in an Appendix – these pages are not counted in your report.

Throughout this assignment you are expected to apply and demonstrate the six steps of problem solving.

You might be asked to demonstrate, discuss or modify your work.

You may supply your word processed documentation in either Microsoft Word or LibreOffice/OpenOffice formats only – no proprietary Mac specific formats, please.

Assignments will be marked on the basis of fulfilment of the requirements and the quality of the work. In addition to the marking criteria, marks may be deducted for failure to comply with the assignment requirements, including (but not limited to):

• Incomplete implementation(s), and
• Incomplete submissions (e.g. missing files), and
• Poor spelling and grammar.

This is an INDIVIDUAL ASSIGNMENT – and while you may discuss it with your fellow students, you must not share designs or code or you will be in breach of the university plagiarism rules.

This IT/Computer Science Assignment has been solved by our IT/Computer Science Experts at My Uni Paper. Our Assignment Writing Experts are efficient to provide a fresh solution to this question. We are serving more than 10000+ Students in Australia, UK & US by helping them to score HD in their academics. Our Experts are well trained to follow all marking rubrics & referencing style.

Be it a used or new solution, the quality of the work submitted by our assignment experts remains unhampered. You may continue to expect the same or even better quality with the used and new assignment solution files respectively. There’s one thing to be noticed that you could choose one between the two and acquire an HD either way. You could choose a new assignment solution file to get yourself an exclusive, plagiarism (with free Turnitin file), expert quality assignment or order an old solution file that was considered worthy of the highest distinction.
