I have a list of tuples ( characters and numbers ) .
say, [('a', 1), ('b', 2)]
I want to extract 'a' and 1 separately .
(x,y) <- head [('a', 1), ('b', 2)]
This doesnt work but my idea is to get x contain the value 'a' and y
contain the value 1 as the first tuple in the list.
Which is the right way of doing this. Thanks for your help.
