Question

reate a function called echoeveryN( ) that takes a non-empty string and an integer, n, as input parameters.  Return from the function every Nth character from the string. For example, echoeveryN("What am I going to say here?",3) would return: 'aaIyn'.  An integer that is out of range (0, negative, or too large)  would simply return an empty string ‘ ‘. Do not use any import libraries as part of the solution. It's OK to use IDLE/PyCharm to test your solution.

Another example call :  echoeveryN("hellotheremyfriend",2) would return 'elteeyred'
