Programming Assignment – Python Functions

 

Your assignment is to read through Chapter 5 – Python Functions and Modularity (included in this week’s Canvas module) and then complete one of two exercises at the end of the Chapter — either  Exercise 5 – International Gymnastics Scoring or Exercise 6 – Test for Divisibility.

You only need to submit the Python source code file, but as the example in the chapter shows, creating your software by

  1. starting with notes,
  2. turning those into comments,
  3. then writing the code to do what the comments say to do

It is a good design process that will help you to manage the growing complexity of the software we are developing. It helps to separate  the logical development of the algorithm from the language of creating the source code.

  1. (a) Do we, as a society, have a special obligation to disabled persons to ensure that they have full Internet access? (b) Is the argument that by providing improved access and services for disabled persons, non-disabled users will benefit as well, a reasonable argument? Consider that it can be dangerous to reason along this line; for example, suppose that non-disabled persons did not benefit from software applications designed for the disabled.

Please elaborate (beyond a yes or no answer) and provide your “theoretical” rationale in support of your responses. (comprehension)
  3. The increased use of expert systems (ES) technology in many professional fields has generated some ethical and social concerns.  Some  ethical controversies surrounding ESs have to do with critical decisions, including life and death decisions; for example, (a) should “expert doctors” be allowed to make decisions that could directly result in the death of, or cause serious harm to a patient? If so, (b) who is ultimately responsible for the ES’s decision? (c) Is the hospital that owns the particular ES responsible? (d) Should the knowledge engineer who designed the ES be held responsible? Or is the ES itself responsible? In answering these questions, you may want to take a look back in chapter 4, specifically the case involving Therac-25. Please elaborate (beyond a yes or no answer) and provide your “theoretical” rationale in support of your responses. (comprehension)
