Question

For this project, you are to modify the Employee class posted on Blackboard by adding a bonus field. The bonus field should be equal to zero when an Employee object is created. You need to add a setter and a getter method to the new bonus field.

The Dirany’s company saves all employee information in the dirany.txt file (attached). The file saves each employee’s information in a new line and all attributes are separated by tabs. For example, the first employee’s information on the first line in the dirany.txt file is as follows:

John    Smith 90000

John is the first name of the employee, Smith is the employee’s last name and 90000 is the employee’s annual salary.

Your program should read the dirany.txt file and create an Employee object for each employee in the file, then add the employees to a queue data structure in the same order you read them from the file. The Dirany’s company saves the employees records according to their longevity in the company.

You need to help the Dirany’s company, to calculate the bonus for each employee according to their longevity rule so the bonus of the first employee will be 20% of his/her salary and for each employee afterwards the percent of the bonus will be 1%less so the second employee will get 19% of his/her salary, the third employee will get 18% of his/her salary and so forth.

Your program should access the Employees’ objects in the queue, calculate the bonus field and set it for each Employee object and display the object status: first name, last name, pay and bonus for each employee.

Also your program should calculate and display the number of the employees in the company and the total bonus that the company will pay for all its employees.

Make sure you break up your code into a set of well-defined functions. Each function should include a comment block that briefly describes it, its parameters and any return values.

John    Smith   90000
Mathew  Marshal 89000
Nicole  Lopaz   88200
Adam    Benjamin        83400
Julia   Hart    82000
Mary    Loveland        79000
Varon   Bansel  73400
Ali     Hassan  63000
Joseph  Murty   52000
Ryan    Frankel 43400
Julianne        Johnson 38600
Noah    Expo    22000
Deven   Williams        19300
Richard Peal    15200

Program

# to use queue import module queue

# employee class defintion

class Employee:

    def __init__(self,firstName,lastName,annualSalary):

        self.firstName=firstName

        self.lastName=lastName

        self.annualSalary=annualSalary

        self.bonus=0

    def getBonus(self):

        return self.bonus

def fillQueuefromFile():

    # fillQueuefromFile function

    # takes not input

    # returns queue of employees loaded from dirany file

    employeeQueue=queue.Queue()

    # initialize queue and open dirany.txt file

    file=open("dirany.txt")

    # read line by line until end of file

    line=file.readline()

    while(line):

        # split the line according to tabs

        tokens=line.split("\t")

        # add to queue an employee object

        employeeQueue.put(Employee(tokens[0],tokens[1],tokens[2][:-1]))

        line=file.readline()

    return employeeQueue

def calculateBonus(employeeQ):

    # calculate bonus function

    # takes input an employee queue

    # returns total bonus paid and the number of employees in queue

    bonus=20    

    # initial bonus

    totalBonusAmt=0

    size=0

    # headers

    print("%10s"%("FirstName"),"%10s"%("\tLastName"),"%10s"%("\t\tPay"),"%10s"%("\tBonus"))

    # loop until the queue is empty

    while not employeeQ.empty():

        emp=employeeQ.get()

        # increment the count for each employee deleted from queue

        size=size+1

        # bonus calculation

        bonusAmt=float(emp.annualSalary)+(float(emp.annualSalary)*(bonus/100))

        # add the bonus to total bonus amount

        totalBonusAmt=totalBonusAmt+bonusAmt

        emp.setBonus(bonusAmt)

        # print the record with formatting

        print("%10s"%(emp.firstName)+"\t"

            +"%10s"%(emp.lastName)+"\t"

            +"%10s"%(str(emp.annualSalary))+"\t"

            +"%10s"%(str(emp.bonus)))

        # bonus can't be negative

        if bonus>0:

            bonus=bonus-1

    return totalBonusAmt,size

# main function calls all other functions

def main():

    employeeQ=fillQueuefromFile()

    totalBonus,size=calculateBonus(employeeQ)

    # print number of employees and total bonus paid

    print("Number of Employees are "+str(size))

    print("Total Bonus paid by company is "+str(totalBonus))

if __name__ == '__main__':

    main()
