But, this effect can be achieved in Python by combining :func:`map` and :func:`count` to form ``map(f, count())``. -The tools also work well with the high-speed functions in the :mod:`operator` -module. For example, the plus-operator can be mapped across two vectors to -form an efficient dot-product: ``sum(map(operator.add, vector1, vector2))``. +These tools and their built-in counterparts also work well with the high-speed +functions in the :mod:`operator` module.
