AssociationThread

AssociationThread[{key1,key2,…}{val1,val2,…}]

给出关联 key1val1,key2val2,….

AssociationThread[{key1,key2,…},{val1,val2,…}]

也给出关联 key1val1,key2val2,….

更多信息

  • 如果任何 keyi 有重复，后来出现的重复键将取代较早出现的键.
  • AssociationThread[keys:>values] 生成一个关联，其中每个元素使用延迟规则.

范例

打开所有单元 关闭所有单元

基本范例  (2)

根据两个列表构成的规则创建关联：

Wolfram Language code: AssociationThread[{"one", "two", "three"} -> {1, 2, 3}]

根据两个独立的列表创建关联：

Wolfram Language code: AssociationThread[{🍎, 🍌, 🍓}, {Today, Now, Tomorrow}]

范围  (1)

创建含有延迟值的关联：

Wolfram Language code: assoc = AssociationThread[{"date", "temp"} :> {DateString[], AirTemperatureData[]}]

获取当前日期和温度：

Wolfram Language code: Values[assoc ]

属性和关系  (2)

重复的键会替换之前的键：

Wolfram Language code: AssociationThread[{1, 2, 1} -> {"eins", "two", "one"}]

AssociationThread[list1list2] 和 AssociationThread[list1,list2] 完全等价：

Wolfram Language code: AssociationThread[{1, 2, 3} -> {Yesterday, Today, Tomorrow}] === AssociationThread[{1, 2, 3}, {Yesterday, Today, Tomorrow}]

如果使用 而非 ，则不成立：

Wolfram Language code: AssociationThread[{1, 2, 3} :> {Yesterday, Today, Tomorrow}] === AssociationThread[{1, 2, 3}, {Yesterday, Today, Tomorrow}]
