No. In idiomatic python, you would not use a functional approach for something like this, but if you really wanted to, you could do:

     def teeing(reducer1, reducer2):
         return lambda acc,elem: (
             reducer1(acc[0],elem),
             reducer2(acc[1],elem)
         )


    functools.reduce(
        teeing(
            (lambda l,elem: [elem] + l),
            (lambda l,elem: elem.price + l)
        ),
        cart.getProducts(),
        ([], 0)
    )
