Solve the following python programming problem given the following code:
def _randint(seed = None) : 
    'Return a randint generator. ``seed`` can be
        o None - return randomly seeded generator
        o int - return a generator seeded with the int
        o list - the values to be returned will be taken from the list
          in the order given.
the provided list is not modified.
