Question

Written in python using puTTy!!

i'm having a lot of trouble with this, will upvote!

also here is the address.csv file

Name,Phone,Email,Year_of_Birth
Elizi Moe,5208534566,[email protected],1978
Ma Ta,4345667345,[email protected],1988
Diana Cheng,5203456789,[email protected],1970

ACTIVITY I

Implement in Python the Subscriber class modeled by the UML diagram provided below. Save in a file called MyClasses.py

Subscriber

name: string

yearOfBirth: int

phone: string

email: string

getName()

getAge()

getPhone()

getEmail()

Write a test program that does the following:

Read the file addresses.csv.
For each record, create an object with the information in the file. Note that the file has 3 records, so 3 objects must be dynamically created.
Print the name, email, and age in a tabulated format as shown below

Name                     Email                           Age

Elizi Moe               [email protected]          40

Ma Ta                    [email protected]          30

Diana Cheng          [email protected]         48

ACTIVITY II

Modify your Subscriber class so that:

The current year is a global variable, taken from the user
The program keeps a count of the number of subscribers instantiated

You must print the same information as in the previous exercise, and in the same format; but also the number of subscribers in the form: “There were xxx subscribers in the file”.

ACTIVITY III

Implement in Python the Subscriber_v2 class modeled by the UML diagram provided below. Save in a file called MyClasses.py

Subscriber_v2

- name: string

- age: int

- phone: string

- email: string

+ getName()

+ getAge ()

+ getPhone()

+ getEmail()

+ setName(name:string)

+ setAge(birthYear:int)

+ setPhone(ph:string)

+ setEmail(email:string)

Write a test program that does the following:

Read the file addresses.csv.
For each record, create an object with the information in the file. Note that the file has 3 records, so 3 objects must be dynamically created.
Print the name, email, and age in a tabulated format as shown below

Name                     Email                           Age

Elizi Moe               [email protected]          40

Ma Ta                    [email protected]          30

Diana Cheng          [email protected]         48

There were 3 subscribers in the file

ACTIVITY IV

Design a class named Stock (add to the file MyClasses.py) to represent a company’s stock that contains:

A private string data field named symbol for the stock’s symbol
A private string data field named name for the stock’s name
A private float data field named previousClosingPrice that stores the stock price for the previous day
A private float date field names currentPrice that stores the stock price for the current time
A constructor that creates a stock with the specified symbol, name, previous price, and current price
A get method for returning the stock name
A get method for returning the stock symbol
Get and set methods for getting/setting the stock’s previous price
Get and set methods for getting/setting the stock’s current price
A method names getChangePercent() that returns the percentage changed from previousClosingPrice to currentPrice

(1) Draw a UML diagram for the class, and then implement the class

(2) Write a test program that creates a Stock object with the stock symbol INTC, the name Intel Corporation, the previous closing price of 20.5, and the new current price of 20.35, and display the price-change percentage

ACTIVITY V

Implement the subclass Rectangle of the the superclass GeometricObject defined by the UML diagram below

GeometricObject -color: str The color of the object (default: green) Indicates whether the object is filled with a color (default: True) filled: bool GeometricObject(color: str, filled Creates a GeometricObject with the specified color and filled boo1) getColorO: str setColor(color: str): None isFilledO: bool setFilled(filled: boo1): None values Returns the color. Sets a new color. Returns the filled property. Sets a new filled property Returns a string representation of this object str__O: str Circle Rectangle -radius: float -width: float -height: float Rectangle(width: float, height: float, color: Circle(radius: float, color: str, filled: bool) getRadius O: float setRadius (radius: float): None getArea O: float getPerimeterO float getDiameterO: float printCircleO: None string, filled: bool) getWidthO: float setwidth (width: float): None getHeightO: float setHeight(height: float): None getAreaO: float getPerimeterO float

Sample Run:

A rectangle color: green and filled: True

The area is 8

The perimeter is 12

Answer 1

ACTIVITY I and II

class Subscriber():
current_year=0
subscriber_count=0
def __init__(self,name,year_of_birth,phone,email):
self.name=name
self.year_of_birth = year_of_birth
self.phone=phone
self.email=email
Subscriber.subscriber_count+=1

def getName(self):
return self.name

def getAge(self):
return Subscriber.current_year-self.year_of_birth

def getPhone(self):
return self.phone

def getEmail(self):
return self.email

def main():
persons=[]
Subscriber.current_year=2018
sub1=Subscriber('Elizi', 1978, '1234567890', '[email protected]')
sub2=Subscriber('Ma Ta', 1988, '1234567890', '[email protected]')
sub3=Subscriber('Diana Cheng', 1970, '1234567890', '[email protected]')
persons.append(sub1)
persons.append(sub2)
persons.append(sub3)
print('{0:<15}{1:<15}{2:>4}'.format("Name","Email","Age"))
for person in persons:
print('{0:<15}{1:<15}{2:>4}'.format(person.getName(),person.getEmail(),person.getAge()))
print('\nThere were', Subscriber.subscriber_count ,'subscribers in the file')
main()

OUTPUT:
