# Dictionary Nodes

Dynamo 2.0 exposes a variety of Dictionary nodes for our use. This includes *create, action, and query* nodes.

#### Create

1.`Dictionary.ByKeysValues` will create a dictionary with the supplied values and keys. *(The number of entries will be whatever the shortest list input is)*

#### Action

2\. `Dictionary.Components` will produce the components of the input dictionary. *(This is the reverse of the create node.)*

3\. `Dictionary.RemoveKeys` will produce a new dictionary object with the input keys removed.

4\. `Dictionary.SetValueAtKeys` will produce a new dictionary based on the input keys and the values to replace the current value at the corresponding keys.

5\. `Dictionary.ValueAtKey` will return the value at the input key.

#### Query

6\. `Dictionary.Count` will tell you how many key value pairs are in the dictionary.

7\. `Dictionary.Keys` will return what keys are currently stored in the dictionary.

8\. `Dictionary.Values` will return what values are currently stored in the dictionary.

Overall relating data with dictionaries is a magnificent alternative to the old method of working with indices and lists.
