Product of the elements in a list

Design goal: should be just one line, without using explicit iteration over the list.

Sum of the elements:

>>> li = [2,3,5]
>>> sum(li)
10

Product of the elements:

>>> li = [2,3,5]
>>> from operator import mul
>>> reduce(mul, li)
30

    Nice simple explanation.
    I sometimes see explanations of for loops with examples of how to use them for summation.
    And I think “No! Just use sum()!”
