:: [Char] -> [Int] -> [(Char, Int)] -package:invertible

zip takes two lists and returns a list of corresponding pairs. zip is right-lazy:

>>> zip [] undefined
[]

>>> zip undefined []
*** Exception: Prelude.undefined
...

zip is capable of list fusion, but it is restricted to its first list argument and its resulting list.

Examples

>>> zip [1, 2, 3] ['a', 'b', 'c']
[(1,'a'),(2,'b'),(3,'c')]

If one input list is shorter than the other, excess elements of the longer list are discarded, even if one of the lists is infinite:

>>> zip [1] ['a', 'b']
[(1,'a')]

>>> zip [1, 2] ['a']
[(1,'a')]

>>> zip [] [1..]
[]

>>> zip [1..] []
[]

zipExact xs ys =
| length xs == length ys = zip xs ys
| otherwise              = error "some message"

Pair two samples. It's like zip but requires that both samples have equal size.
