159.171 - Assignment 3 – 2019
Worth: 20% of final mark
Due date: 6pm Friday, May 31st
For all two programs:
use meaningful names for variables and functions.
add any comments you think will help explain what your program's doing
Question 1: Random Real Estate Advertisement Generator (10 marks)
Write a program that reads in a file of properties and produces random but realistic advertisements,
according to the rules specified on the next page.
Here are two examples:
*** Your Brand New Home ***
Spacious 2 bedroom home in Hokowhitu.
Would suit a retired couple.
Close to hospital.
Price $320,000.
All enquires to John on 021-027-1234.
*** Make it yours today! ***
*** Your New Family Home ***
Wonderful 3 bedroom home in Terrace.
Would suit a professional couple.
Close to motorway.
Price Auction.
All enquires to Joe on 183-007-1239.
*** Make it yours today! ***
It does this by randomly choosing properties that meet certain criteria.
The basic structure of your advertisement is below, where parts in <...> are words/phrases to
be randomly selected from the lists:
*** Your Home ***
bedroom home in .
Would suit .
Close to .
Price .
All enquires to on .
*** Make it yours today! ***
Randomly choose an item from the following lists to fill in the description, adjective, and type of
owner, but the word selected for description must meet the rules specified on the next page.
description = ['First', 'Dream', 'New Family', 'Brand New']
adjective = ['Wonderful', 'Sunny', 'Spacious', 'Secluded']
type_of_owner = ['a couple', 'a family', 'a retired couple',
‘a large family', 'a professional couple'] 159.171 Assignment 3 Page 2 of 6
Randomly choose a property from properties.txt (download it on Stream) to fill in the number
of bedrooms, suburb, amenities close by, price, agent name and agent phone based on the
selected type of owner and the rules specified in the below table.
In properties.txt, each line is the detailed information of a property: each part is separated by a
hyphen (“-”); nearby amenities are connected by a colon (“:”). The following is an example of a
property:
no of bathrooms
Albany-3-2-$670000-great schools:bus station:shopping centre-John-0234513456
suburb price amenities close by agent name agent phone

no of bedrooms
The detailed information of this property is:
suburb: Albany
no of bedrooms: 3
no of bathrooms: 2
price: $670,000
amenities close by: great schools, bus station, shopping centre
agent name: John
agent phone: 023-451-3456
According to the rules specified in the above table, this property is suitable for a family owner or
a professional couple owner. For other types of owner (a couple, a retired couple, and a big
family), this property is unable to meet their criteria.159.171 Assignment 3 Page 3 of 6
Commands
Make the following commands available using a menu and prompt for a command. The commands
can be upper or lower case (e.g. e or E) or either. It'll be easier if you implement the commands in
order (L first ...)
CMD Effect
L Load properties.txt from disk to form a property list.
T Test: display the first two properties from the property list to make sure they've
been loaded.
E
Easy advertisement: display an advertisement -- a randomly selected property
from the property list and randomly selected words from description, adjective
and type_of_owner lists.
R
Real advertisement: generate & display a real estate advertisement conforming
to the rules specified on the previous page. If the wordlists haven't been loaded,
display an error message.
S
Search: Prompt for a type of owner, and then search for all properties that meet
this type of owner’s criteria specified on the previous page. Next sort these
properties by price. Finally produce & display three advertisements: one is for a
property with the lowest price; second is for a property with the highest price;
third is for a property by Auction. Search case-independently. If the search string
is empty, exit the search and redisplay the menu.
Q Quit the program.
For full marks
The sentences in the advertisement should be capitalised correctly and have a trailing full
stop.
Words for description, suburb, and name should be capitalised.
Price has two types of value: one is amount, another is Auction. The format for price is
$11,111,111 or Auction.
The formats for phone should be 11-111-1111. 159.171 Assignment 3 Page 4 of 6
Question 2: Student Profiles (10 marks)
Using a dictionary indexed by student ID, write a simple Student Profiles that lets you save
these profile details.
Here student ID is composed of 7 digital numbers and always starts with 192. It should be
generated automatically. Each student’s ID should be unique.
The usercode is composed of the first letter of the student’s first name and the student’s last
name, if there are duplicates, append a number to distinguish them. Each student’s usercode is
unique. For example,
Student Name Usercode
Xing Chen xchen
Alan Wang awang
Xiaoping Chen xchen1
John Truter jtruter
Xiaoai Chen xchen2
When adding Xiaoping Chen to the Student Profiles, xchen already exists, so this
student’s usercode becomes xchen1.
While Xiaoai Chen is added, there already have two xchen in the Profiles, so xchen2 is
this student’s usercode.
Once the name of a student is known, the program should automatically generate this
student’s usercode.
Each dictionary entry contains a dictionary of the details of that student, so
students['1920001'] # will return the dictionary that contains details of
a student whose ID is 1920001,
and
profiles = students['1920001']
address = profiles['address']
or simply
address = profiles['1920001']['address']
will return the address of the student whose ID is 1920001.159.171 Assignment 3 Page 5 of 6
The program first displays a menu (something like that shown below) and carries out the
appropriate action depending on which letter the user types, and then redisplays the menu:
find prompt for a usercode or student ID, then search for the name, address, email
and phone number of the student with this usercode or ID in Student Profiles
and display their details. Make the search is case-insensitive.
add prompt separately for each of name, address, email, and phone-no. Then
automatically generate this student’s ID and usercode and save all of these
fields into a data structure. A dictionary is recommended but a list will also
work.
delete prompt for a usercode or student ID, then find and display the related entry.
Ask the user if this is the correct one to be deleted. If they reply "yes", delete
it.
modify prompt for a usercode or student ID, then prompt for a field, e.g. name,
address, email, or phone-no. Next prompt for a new value for the field.
Display the student’s detail. Ask the user if this is the correct student and is
the right field to be modified. If they reply "yes", replace this field with the
new value.
list all As expected list all the entries, numbered sequentially. Display all the fields
and format them for easy reading. Down and cross layouts are shown below.
Down
ID Name Usercode Address Email Phone
1 1920001 Sue Chen schen 104 Broad Way schen@massey.co.nz 021-334-2312
2 1920002 Robert Lee rlee 25 Ritzherbert Ave rlee@massey.co.nz 021-489-8865
The Student Profiles - Getting Started:
get the menu going and then create a function for each of list-all, add, ... Initially, simply
put a print inside each function, e.g. for the addEntry function, put print("You called
ADD"). You can test each command – they'll simply print out a message.
using an assignment statement, manually create a tiny Student Profiles containing two or
three entries
get the list-all command going. You can use this to view your manually created Student
Profiles and effects of the later commands
then work on add, find, delete and modify
to abort the add command (and find/delete/modify), simply enter an empty string.
IMPORTANT:
make sure that there are no duplicates for Student IDs and Usercodes,
make sure that you use functions, usually one for each of the commands. You can of
course, create any additional functions that you think will help to simplify or clarify your
code.
Optional (you can get full marks without doing this): you could try adding a s (search)
command that searches for and displays all entries that have the search string in any of the fields
(not just the ID or usercode).
What and how to submit
How: ALL submissions must be via Stream (not email) using the Assignment 2 submission link.
What: Submit your Python programs, each named with .py extensions. You should have three .py
files to submit, one for each question.
Do not submit Word documents (.doc or .docx) or .zip or .rar files.
Check:
that your files have a .py extension
that all programs display your name and your Massey Student ID number when starting.
