For Python, we don't need to supply the optional initializer 1. And reduce resides in the functools namespace (much like mul is in operator). I assume we're not talking about that peculiar dialect of Python that is no longer supported a few months from now.

Not only that but in python 3.8, it can be written:

    def factorial(n):
        return math.prod(range(1,n+1))

Without the initializer, factorial(0) doesn't work.
