Using the Python program, create a program that prints out a list of 15 words in a random order AND does not repeat any words!

The 15 words: easter, people, April, spring, vacation, basketball, flowers, memorial, field, grass, temperature, grandpa, grandma, morning, and sunset.

Then you will add the ability of the user to add a new word to this list and display the new list. This must be able to repeat multiple times.
