Some pointers:

    * An even number divided by 2 gives a remainder of 0, an odd number
      divided by 2 gives a remainder of 1.
    * There are functions/operators that give you the remainder of a
      division of one number by another (hint, "modulo")
    * Indices into a string are just numbers

Alternates:

    * Look at the "range" function's parameters (think indices)
    * If you're using a later version of Python, look at the "stride"
      available in slices
    * Brute force (track on/off for each item) will work, but be rather ugly

Good luck,
Mike
