  # Print first and last name in reverse order with a space between them
  # In python there are two functions designed to accept data directly from a user.
      # Python 2.x -> raw_input()
      # Python 3.x -> input()
  
  # raw_input() asks the user for a string of data and simply returns the string, the string data ended with a 
  # newline. It can als take an argument, which is displayed as a prompt before the user enters the data
  
  #input():
  # In 3.x. raw_input() is renamed to input(). input() function reads a line from sys.stdin and returns it with the trailing newline stripped. To assign the user's name to a variable "y" use the command:
  
  # y = input('Input your name')
  
  # fname = input("Input your first name : ")
  # lname = input("Input your last name : ")
  # print("Hello " + lname + " " + fname)
