Get a sublist in Haskell

Question

Probably an easy one, but I\'ve looked through the docs and googled for examples and I\'m still not sure of the answer.

If I have a list like this:

[1,2,         


        

Answer 1

Hmmm, not very practical, but maybe it can be improved?

(\(x,y) -> if 4 <= y && y <= 9 then [x] else []) =<< zip [1,2,3,4,5,6,7,8,9] [0..]
