Merge String Lists

This List tool merges two lists of strings and returns the appended list, the intersection of the two lists, or the union of the two lists. The optional Boolean input, when set to True, allows for clearing the source lists.

Note: This tool is useful when you have two lists to check and you want to avoid looping through each item in each list.

Inputs

Mode

The type of merge to perform:

Value	Mode	Description	Example
Value	Mode	Description	Source List 1	Source List 2	Merged List
0	Intersect	The merged list contains only the items that are included in both source lists.	1, 2, 3	1, 3, 4	1, 3
1	Union	The merged list contains one instance of each item in the source lists.	1, 2, 3	1, 3, 4	1, 2, 3, 4
2	Append	The merged list contains all items from both lists.	1, 2, 3	A, B, C	1, 2, 3, A, B, C

Empty source lists?

Set this Boolean parameter to True to empty the source lists of strings, reducing the memory used to store the lists. This parameter is optional and defaults to False.

Outputs

Source List 1

The first source list of strings to merge.

Source List 2

The second source list of strings to merge.

Merged List

The resulting merged list.
