Write a Python program in the file helloworld.py that uses the assignment operator to assign the message hello world to the string variable greetings.
You will write your solution in a method called displaymessage(), right below the place where it says: YOUR CODE HERE. Make sure that the phrase hello world is placed in the variable greetings. Save your code by using the keystroke combination Ctrl-s.

Method call

The output of your program should appear in the Console at the bottom of your window. You should see the words hello world displayed on the output.
