AssociationThread

AssociationThread[{key1, key2, ...} -> {val1, val2, ...}] or AssociationThread[{keys}, {values}] creates an association pairing corresponding keys and values.

Examples

Create an association from two lists:

AssociationThread[{"a", "b", "c"}, {1, 2, 3}]
(* <|"a" -> 1, "b" -> 2, "c" -> 3|> *)

(* Using rule form *)
AssociationThread[{"x", "y"} -> {10, 20}]
(* <|"x" -> 10, "y" -> 20|> *)
