[Haskell-beginners] generating by mapping

[Stephen Tetley]

Hi Szilveszter

zipWith is probably what you are after...

> zipWith Stuff nums strs
[Stuff {aNum = 123, anStr = "qwe"},Stuff {aNum = 321, anStr =
"asd"},Stuff {aNum = 345, anStr = "zxc
"}]

Note zipWith (and the function zip which it generalizes) go 'short' -
i.e. if one of the input lists is shorter than the other - the size of
the result list will the size of of the shorter one:


> zipWith Stuff [1] strs
[Stuff {aNum = 1, anStr = "qwe"}]


Best wishes
