Question

In python, The function slice_end takes a string parameter, word, and a positive integer n; the function returns a slice of length n from the end of word. However, if word has length less than n, then the None object is returned instead.

Hint: Notice that returning the empty string when n is zero might be a special case.

You can use an if-elif-else decision structure and the slicing operator [ : ] to solve this problem.

For example:

Test	Result
word = "pineapple" n = 5 print(slice_end(word, n))	apple
word = "too short" n = 20 print(slice_end(word, n))	None
word = "llama" n = 0 print(slice_end(word, n))
word = "Saturn" n = 6 print(slice_end(word, n))	Saturn
