Assignment 10

CS 0002 Section 8

For this assignment you will be writing a single program to solve all the problems in it, which you

should submit on Brightspace.

If you work with another person on your program, please be sure to credit them in the comments in

the header of the program. Remember to comment your program well and to put a header at the

top of the program with your name, the course number and section, the date, and the assignment

number.

Document every function you write with an “input-processing-output” (IPO)-style header. You

should do this for all the functions you write in this class.

You may not use any Python modules in doing this assignment, because there are some

modules, like the “csv” and “pandas” modules, which would make doing it much easier, and the

point of the assignment is for you to learn how to process data from a file using the basic file

operations taught in class.

Problem #1: A Real Estate Database, Redone

Redo the program to construct a real estate database of assignment 8, problem 5, but instead

construct the following nested dictionary.

realEstate = {"Studio Condo": {'sqfootage':400,'bedrooms':0,'price':100000},

"Charming Cottage": {'sqfootage':800,'bedrooms':1,'price':200000},

"Ranch": {'sqfootage':1200,'bedrooms':2,'price':300000},

"Tudor-Style Home": {'sqfootage':2400,'bedrooms':3,'price':500000},

"Georgian-Style Mansion": {'sqfootage':6000,'bedrooms':8,'price':2000000}}

You should implement the same inputs as follows as in the earlier problem (user input is

underlined):

Enter a home description, enter stop to exit: Studio Condo

Enter the square footage: 400

Enter the number of bedrooms: 0

Enter the price: 100000

Enter a home description, enter stop to exit: Charming Cottage

Enter the square footage: 800

Enter the number of bedrooms: 1

Enter the price: 200000

Enter a home description, enter stop to exit: Ranch

Enter the square footage: 1200

Enter the number of bedrooms: 2

Enter the price: 300000

Enter a home description, enter stop to exit: Tudor-Style Home

Enter the square footage: 2400

Enter the number of bedrooms: 3

Enter the price: 500000

Enter a home description, enter stop to exit: Georgian-Style Mansion

Enter the square footage: 6000

Enter the number of bedrooms: 8

Enter the price: 2000000

Enter a home description, enter stop to exit: stop

But when you are done with your inputs, just print the dictionary which should be the same as the

nested dictionary given above (if you give the inputs shown above).

Grading: Five points correct logic, three points correct output, two points comments

Problem #2: Real Estate Database Search, Redone

Redo the real estate database search of assignment 8, problem 5, but instead use the following

nested dictionary as described in problem 1 which you can “wire” at the beginning of your program

(that is, just put the following code there).

realEstate = {"Studio Condo": {'sqfootage':400,'bedrooms':0,'price':100000},

"Charming Cottage": {'sqfootage':800,'bedrooms':1,'price':200000},

"Ranch": {'sqfootage':1200,'bedrooms':2,'price':300000},

"Tudor-Style Home": {'sqfootage':2400,'bedrooms':3,'price':500000},

"Georgian-Style Mansion": {'sqfootage':6000,'bedrooms':8,'price':2000000}}

Grading: Five points correct logic, three points correct output, two points comments

Problem #3: Read the Watch Data into a Nested Dictionary (10 points)

Read the watch data from the assignment 9 into a nested dictionary where the top-level keys are

the line numbers (starting with zero) are the top-level keys and the values are themselves

dictionaries with keys “brand”, “description, “price” and “discount”. Print out the first five records of

this nested dictionary as follows:

0 {'brand': 'fastrack wearables', 'description': 'unisex reflex curv pink strap silicone digital

watch', 'price': 4495, 'discount': 31}

1 {'brand': 'fastrack wearables', 'description': 'unisex 40 mm reflex slay charcoal black dial

silicone smart watch', 'price': 3995, 'discount': 33}

2 {'brand': 'titan', 'description': 'mens 52.50 x 11.70 x 44 mm octane black dial leather analog

watch - 90107kl01', 'price': 3997, 'discount': 50}

3 {'brand': 'timex', 'description': 'men fashion green multifunction strap wrist watch', 'price':

3596, 'discount': 20}

4 {'brand': 'police', 'description': 'mens grey leather multi-function watch - pl15472jsu61',

'price': 7977, 'discount': 40}

If the dictionary you create had only the first three records, it would look like the following:

{0: {'brand': 'fastrack wearables', 'description': 'unisex reflex curv pink strap silicone

digital watch', 'price': 4495, 'discount': 31}, 1: {'brand': 'fastrack wearables', 'description':

'unisex 40 mm reflex slay charcoal black dial silicone smart watch', 'price': 3995, 'discount':

33}, 2: {'brand': 'titan', 'description': 'mens 52.50 x 11.70 x 44 mm octane black dial leather

analog watch - 90107kl01', 'price': 3997, 'discount': 50}}

But put all of the records in the dictionary.

Grading: Five points correct logic, three points correct output, two points comments

Problem #4: Find the Brand Count, Most Expensive Watch, and Average

Watch Price using the New Data Structure (10 points)

Find the brand count, most expensive watch, and average watch price again, but using the new

dictionary-based data structure described above.

Print the brand count by creating and printing out a dictionary where the keys are the brands and

the values are the counts.
