title: creating a list containing list of employees
body: <p>I need to create a program that contains a list of employees in a company. The program should allow for the addition of employees to the list as they join the company. When an employee leaves the company, the program should find their index number in the list and replace their name with the name of a new employee.</p>
  
  <p>this is what I've done so far, i think it's nearly finished, could someone help me finish it please??</p>
  
  <pre><code> def main():
  
       #create list
       employee = ["Ciara Murphy", "Shauna Williams", "Sarah Kelly", "Evana Leanne"]
  
       #print list
       print(employee)
  
       #print item at line index 2
       print(employee[2])
  
       #insert at index 3
       employee.insert(3, "Alana Marie")
       print(employee[3])
  
       #try
       print(employee.index("Sarah Kelly"))
  
   main()
  </code></pre>
  
  <p>I'm using python 3.3.2</p>
