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.

Thanks...
