yup, not sure what Python does with your examples under the hood, but they're equivalent, and, I must say, nicely concise ;-)

In Scala I guess we could go zip-style and do:

    List(1,2,3) zip List(4,5,6) map{case(x,y)=> x*y}

but I was trying to demo for comprehensions and their relation to map/flatMap for the OP.
