KeyValueMap
KeyValueMap[f,key1val1,key2val2,…]
gives the list {f[key1,val1],f[key2,val2],…}.
KeyValueMap[f]
represents an operator form of KeyValueMap that can be applied to an expression.
Details
- KeyValueMap[f][assoc] is equivalent to KeyValueMap[f,assoc].
- Parallelize[KeyValueMap[f,key1val1,key2val2,…]] computes KeyValueMap[f,key1val1,key2val2,…] in parallel on all subkernels. »

Map a function over the keys and values of an association:
KeyValueMap[f, <|a -> 1, b -> 2, c -> 3|>]Use the operator form of KeyValueMap:
KeyValueMap[f][<|a -> 1, b -> 2, c -> 3|>]Properties & Relations (3)
KeyValueMap[f,assoc] is equivalent to MapApply[f,Normal[assoc]]:
KeyValueMap[f, <|a -> 1, b -> 2, c -> 3|>]% === MapApply[f, Normal[<|a -> 1, b -> 2, c -> 3|>]]KeyValueMap maps a function over the keys and values in an association (and returns a list):
KeyValueMap[f, <|a -> 1, b -> 2, c -> 3|>]AssociationMap maps a function over the rules in an association:
AssociationMap[Reverse, <|a -> 1, b -> 2, c -> 3|>]KeyMap maps a function over the keys in an association:
KeyMap[f, <|a -> 1, b -> 2, c -> 3|>]Map maps a function over the values in an association:
Map[f, <|a -> 1, b -> 2, c -> 3|>]KeyValueMap can be parallelized automatically:
