I don't know what the mult function is there for,
since you're not using it in that example. All you
need is

  f = reduce(lambda x,y: x*y,n)

It's a matter of taste. Some people like the ability
to write very trivial functions like your mult() in-line.
Others find it clearer to define them separately.
If you like the separate version better, feel free
to use it.
