use python

Write a function called get_nth(str_list, n), which takes in two integer parameters, str_list, which is a list of words (strings), and n, which is an integer The function should return a string that is composed of nth letter in the nth word in the list, repeated n times. Note that when we say nth letter/ nth string in this case, we are counting starting at 1, for example s is the 4th letter in prismatic, even though it is index 3 because Python starts counting at 0. You can assume n will be a positive integer, and that the list will have its nth string have at least n letters.
