There are two questions in this assignment. For each question you will be submitting your

solution as multiple files, each containing source code written in Python 3. These files must be

compressed into a single “zip” file, and you will submit this file using cuLearn.

 The source files for question 1 must be named “a2q1a.py”, “a2q1b.py”, and “a2q1c.py”

 The source files for question 2 must be named “a2q2a.py” and “a2q2b.py”

 The compressed archive (i.e., the .zip file) must be named “a2.zip”.

 

You are expected to demonstrate good programming practices at all times (e.g., choosing

descriptive variable names, provide comments in your code, etc.) and your code will be

penalized if it is poorly written.

You are expected to do the necessary preparatory work (e.g., devising an algorithm) before

you begin coding. Whenever appropriate, you will be asked to present either pseudocode or a

flowchart before you will receive any assistance from the instructor or a teaching assistant.

This assignment is uniquely generated; every student in the class is required to complete a

slightly different version of this assignment. To ensure that each unique assignment shares the

same level of difficulty, a unique assignment generator (and supporting files) has been made

available on cuLearn.

To receive the assignment instructions that are specific to you, download the

“unique-assignment-generator-for-A2.zip” file from cuLearn. Once you have extracted the

contents to your working folder, use the command prompt to run the “generator-for-A2.py”

program and then enter and confirm your student number.

Question 1 (of 2)

When you ran the unique assignment generator for this assignment, the program showed you a

collection of 18 cartoon faces as the top three rows of the SimpleGraphics window. For the first

question of this assignment you will create three short programs that will ask the user

questions as though the user is playing a game of “Guess Who?” using this collection of faces. If

you are completely unfamiliar with this game you should consider visiting the Wikipedia page

(https://en.wikipedia.org/wiki/Guess_Who%3F) and playing an online implementation (such as

the one at http://www.miniplay.gr/?view=game&gid=76).

Each of the programs you write will require you to use the input function to ask the user one or

more yes or no questions. You MUST restrict your questions to asking about whether or not the

player’s choice of face has a wig, glasses, hat, pipe, moustache, beard, or scar, and each

question can only ask about one of those features. To clarify, you are NOT permitted to ask

questions pertaining to the row, column, eyes, mouth, or any feature other than the seven

listed above.

Your first program (i.e., “a2q1a.py”) must contain a single if statement that does not use any of

the Boolean operators (i.e., and, or, not), has no elif or else branches, and would only work to

identify one specific face (i.e., ending the game with a single question). To clarify, you can

assume that your program will win if the opponent (i.e., the user) has chosen the only face out

of group of eighteen that can be identified by a single question. For further clarification,

consider the collection of three faces below and note that the only single question that could

conceivably identify one of these three is the question “Are you wearing a hat?”

Your second program (i.e., “a2q1b.py”) must contain a single if-else statement that does not

use any of the Boolean operators (i.e., and, or, not), has only a single else branch, and is

guaranteed NOT to identify your opponent. To clarify, regardless of which face your opponent

has chosen, they should end up following the else branch of your statement.

Your third program (i.e., “a2q1c.py”) must contain a single nested if statement with a depth of

two (i.e., one “inner” if statement nested inside one “outer” if statement) that does not use any

of the Boolean operators (i.e., and, or, not). Write this program such that exactly five possible

choices of face should pass the condition of the outer if statement, and only one of those faces

should pass through the condition of the inner if statement.

Question 2 (of 2)

When you ran the unique assignment generator for this assignment, the program also showed

you a collection of 10 arrows as the bottom two rows of the SimpleGraphics window. For the

second question of this assignment you will create two expert systems that will allow the user

to uniquely identify each of these arrows by answering a series of questions.

An expert system represents to a solution to a categorization problem. An expert system is

expected to maintain a database that contains the identity of each element of a large

collection, and then when a user has an unknown element they would like to identify they can

answer questions from the expert system and the expert system can identify the unknown

element. As a clarifying example, suppose the database maintained by an expert system

contained the following four arrows (denoted arrows 1, 2, 3, and 4, respectively)…

…and the user encountered the following unknown symbol, to be identified:

The expert system might ask the user “Does the symbol use any curved lines?” and if the user’s

answer is “yes” then the expert system knows the unknown symbol must be either 1 or 2. The

expert system might then ask “Does the symbol point straight upwards?”, etc.

Your first expert system (i.e., “a2q2a.py”) must use a single if-elif-else statement to correctly

identify each of your ten symbols, and this statement must be flat (i.e., not nested). For this

question you are only permitted to ask the user yes or no questions. To accomplish this you will

need to use Boolean operators (i.e., and, or, not) and create conditions such that each

condition only evaluates to True for a single arrow. As a clarifying example you might create the

following flat if statement (for the example included above):

if isCurved == “yes” and isUpwards == “yes”:

print(2)

elif isCurved == “yes” and not(isUpwards == “yes”):

print(1)

Your second expert system (i.e., “a2q2b.py”) must use a single nested if statement to correctly

identify each of the ten symbols that you have been assigned. This system is expected to ask as

many non-yes or no questions as possible (e.g., “How many solid parts make up the symbol?”)

but it must not ask any unnecessary questions. This entails that, unlike your first expert system,

 

your second system cannot ask all the questions
