Question
Write a function that will accept a list of numbers and an integer (n). The
function should return a list containing every nth item from the input list,
always starting with the first item in the list. The original list should not
be modified.
For example, if the function is passed the list
[8, 3, 19, 26, 32, 12, 3, 7, 21, 16]
and the integer 3, it will return the list
[8, 26, 3, 16]
The function should be general, and work for any list and any positive
integer value of n.
def countByN(myList,n):
return myList[::n]
