Lists

Workflows supports lists (or arrays) for storing data.

List definition

Lists can be created in a workflow by being returned as the result of a step or by being defined in an assign step.

Update list items

You can update the value at an index by using an assign step and index notation.

my_list(len(my_list) - 1)

Add a new item to the end of a list

You can create a copy of a list with a new element concatenated at the end by using the list.concat function.

list.concat(my_list, "Kiwi")

Check existence of a key in a list

To check whether a given key is present in a list, use the following expression:

"Kiwi" in my_list

To check whether a key is not in a list, use the not() function:

not("Kiwi" in my_list)
