Re: [Haskell-cafe] How to join two lists of lists?

Hi all! I'm trying to join to lists of lists. The problem is, i would like to get a new list of lists of tuples and not list of tuples of lists (that what zip makes).

list1 = [[1,2],[3,4],[5,6]] list2 = [[a,b],[c,d],[e,f]]

desiredlist = [[(1,a),(2,b)],[(3,c),(4,d)],[(5,e),(6,f)]]

Prelude> let list1 = [[1,2],[3,4],[5,6]] Prelude> let list2 = [['a','b'],['c','d'],['e','f']] Prelude> zipWith (zip) list1 list2 [[(1,'a'),(2,'b')],[(3,'c'),(4,'d')],[(5,'e'),(6,'f')]] Why do you want to do this?
