> Hi,

> I have the following two lists:
> 
> a = [1,2,3]
> b = ["A","B","C"]
> 
> I want a combination of the to lists:
> 
> c = [(1,"A"), (2, "B"), (3, "C")]
> 
> How can I do this?
> 
> I have tried
> 
> c = [(x,y) | x <- a, y <- b] 
> 
> But this  just returns me a list with every possible combination of the 2
> lists.
