Write a class named Employee that holds the following data about an employee in attributes: name, ID number, department, and job
viktelen [127]

firstly we have to create class and then constructors and method

let start with class

class Employee:

   def __init__(self, name, id, department, title):

       self.__name = name

       self.__id = id

       self.__department = department

       self.__title = title

   def set_name(self, name):

       self.__name = name

   def set_id(self, id):

       self.__id = id

   def set_department(self, department):

       self.__department = department

   def set_title(self, title):

       self.__title = title

   def get_name(self):

       return self.__name

   def get_id(self):

return self.__id

   def get_department(self):

       return self.__department

   def get_title(self):

       return self.__title

def __str__(self):

       return 'Name: ' + self.__name + \

              '\nID number: ' + self.__id + \

              '\nDepartment: ' + self.__department + \

              '\nTitle: ' + self.__title

Now to test the program

import emp

def main():

   emp1 = emp.Employee('name', 'id', 'department', 'title')

   emp2 = emp.Employee('name', 'id', 'department', 'title')

   emp3 = emp.Employee('name', 'id', 'department', 'title')

 

   emp1.set_name('Susan Meyers')

   emp1.set_id('47899')

   emp1.set_department('Accounting')

   emp1.set_title('Vice President')

   emp2.set_name('Mark Jones')

   emp2.set_id('39119')

   emp2.set_department('IT')

   emp2.set_title('Programmer')

   emp3.set_name('Joy Rogersr')

   emp3.set_id('81774')

   emp3.set_department('Manufacturing')

   emp3.set_title('Engineer')

   print()

   print(emp1)

   print()

 print(emp2)

   print()

   print(emp3)

main()
