Question

PYTHON: The following puzzle is known as The Big Cross-Out Swindle.“Beginning with the word ‘NAISNIENLGELTETWEORRSD,’ cross out nine letters in such a way that the remaining letters spell a single word”. Write a program that creates variables named startingWord, crossedOutLetters, andremainingLetters. The program should assign to startingWord the string given in the puzzle, assign tocrossedOutLetters a list containing every other letter of startingWordbeginning with the initial letter N, and assign to remainingLetters a list containing every other letter of startingWord beginning with the second letter, A. The program should then display the values of the three variables.
