You may not use any list functions other than len(), pop(), extend() and append().

List slices ARE allowed using the [:] operator if you want.

Your younger cousin keeps asking for the same stories told over and over again. Youve decided to automate the storytelling with a Python program. Your function tell_story should take in a list of strings in story, and then print the story from the list according to the direction variable:

forwards: tell the story in the order its presented in the list

backwards: tell the story backwards

every other: tell your cousin only every other line in the story.

Your function should choose an ending to the story depending on the input ending type:

happy: and they all lived happily ever after.

sad: but alas, it did not last.

Anything else: and thats all Im going to say about that. The story should be printed to the terminal according to the instructions in ending and direction. The ending of a story always

comes at the end, no matter what the direction of the story is.
