intersperse :: a -> [a] -> [a]listsafe Data.List.Safe The intersperse function takes an element and a list and `intersperses' that element between the elements of the list.
Laziness
intersperse has the following properties>>> take 1 (intersperse undefined ('a' : undefined)) "a">>> take 2 (intersperse ',' ('a' : undefined)) "a*** Exception: Prelude.undefinedExamples
>>> intersperse ',' "abcde" "a,b,c,d,e"
>>> intersperse 1 [3, 4, 5] [3,1,4,1,5]
data
Intersperse (b :: a) (c :: [a]) (d :: [a])first-class-families Fcf.Data.List Intersperse a separator between elements of a list.
Example
>>> :kind! Eval (Intersperse 0 [1,2,3,4]) Eval (Intersperse 0 [1,2,3,4]) :: [Natural] = [1, 0, 2, 0, 3, 0, 4]
