范例

基本范例 (3)

创建关联：

Wolfram Language code: assoc = Association[{a -> 1, b -> 2, c -> 3}]

改变与 a 关联的值：

Wolfram Language code: AssociateTo[assoc, a -> 11]

如果键尚未在关联中，它将被添加：

Wolfram Language code: AssociateTo[assoc, d -> 4]

改变关联中的多个值：

Wolfram Language code: assoc = Association[{a -> 1, b -> 2, c -> 3}]

Wolfram Language code: AssociateTo[assoc, {b -> 22, c -> 33, d -> 44}]

将一个关联追加到另一个上：

Wolfram Language code: assoc = Association[{a -> 1, b -> 2}]

Wolfram Language code: assoc2 = Association[{c -> 3}]

Wolfram Language code: AssociateTo[assoc, assoc2]
