For loops python problems

Question

Write a function that takes as an input parameter a string and a number n and returns a newly created string made of every nth letter.

Can anyone help?

What have you tried? Have you looked at any string methods, in particular `slice notation`? — sberry, Nov 12 '11 at 02:19

This is quite simple in Python because of the way it handles indexing:

def every_n(s, n):
    return s[::n]

That third item between the colons says "every n".

Check out Explain Python's slice notation for a more in depth description of how to slice in Python.
