Programming Exercise #6 (Employee Management System): Use the Contact Manager Sy

Question

Programming Exercise #6 (Employee Management System): Use the Contact Manager System from pages 456 to 462 as a guide. You will be using a dictionary, a menu system, and pickling to create your system. In most cases, you are simply changing the word “contacts” to “employees”.

a.Name your Python file employee_manager.py

b.The modules will be pretty much the same as in the Contact Manager System, except that you have four attributes in the Employee class, not three.

c.Test your program by adding the three Employee objects from page 479, then changing some attributes, deleting some employees, and adding your own. Close the program and start it again, to make sure your information is saved between sessions.

Explanation / Answer

//This is my Employee Class with four attributes: ID, number, dept and title

class Employee:
'ID, number, dept, jobTitle'

def __init__(self,ID,number,dept,jobTitle):
self.ID = ID
self.number = number
self.dept = dept
self.jobTitle = jobTitle

  
   #Defining the setter and getter mothods:
  
   def set_ID(self,ID):
self.ID = ID

def set_number(self,number):
self.number = number

def set_dept(self,dept):
self.dept = dept

def jobTitle(self,jobTitle):
self.jobTitle = jobTitle

def get_ID(self):
return self.ID

def get_number(self):
return self.number

def get_dept(self):
return self.dept

def get_jobTitle(self):
return self.jobTitle

def get_data(self):
print self.ID, self.number,self.dept,self.jobTitle

//Creating employee objects
      
import Employee

filename = 'contact_manager.dat'
my_file = open(filename,'rb')
unpickle_my_file = pickle.load(my_file)
def test_scenario():

user = input('Press 1 to Get Details of an employee, Press 2 to add employee'
' 3Press 3 to change an existing employee name, dept and job title'
' 4 Delete an employee from the dictionary'
' 5 Quit the program'
' Make your choice ')

if user == 2:
ID = raw_input('Enter the name ')
number = input('Enter the number')
deparment = raw_input('Enter the dept ')
jobTitle = raw_input('Enter the job title ')

entry = module from Employee??.class name(id,number,dept,jobTitle)??
empty_dictionary = {}
empty_dictionary[number] = entry
       entry = Employee.Employee(id, number, dept, jobTitle)      
      
   if user==3
       ID = raw_input('Enter the ID to whom you want to make changes ')
       entry = module from Employee??.class name(id,??,??,??)??  
       number = input('Enter the New number')
deparment = raw_input('Enter the New dept ')
jobTitle = raw_input('Enter the New job title ')  
       empty_dictionary = {}
empty_dictionary[number] = entry  
       entry = Employee.Employee(id, number, dept, jobTitle)      

   if user==4
       ID = raw_input('Enter the ID to whom you want to make changes ')
       entry = module from Employee??.class name(id,??,??,??)??  
       empty_dictionary[number] = entry  
       print delete_Emp_Entry(empty_dictionary,ID);

my_file.close()

def delete_Emp_Entry(dict, key):
del dict[key]
return dict
