Iterator: Zip

Combine multiple input lists into a single list of tuples (each tuple is a JSON array). Wire each list to its own slot on the unlimited arr input.

By default the result is truncated to the length of the shortest input. Use Strict to fail instead, or Fill value to pad shorter inputs to the longest input's length ("zip longest").

Example
Inputs:  [1, 2, 3], ["a", "b", "c"]
Output:  [[1, "a"], [2, "b"], [3, "c"]]

Inputs:  [1, 2, 3], ["a", "b"]
Default: [[1, "a"], [2, "b"]]                  (truncate)
Strict:  error
Fill="?": [[1, "a"], [2, "b"], [3, "?"]]       (pad)

Parameters​

Strict

When enabled, fail the step if the input lists have different lengths. Mutually exclusive with Fill value.

Fill value

"Zip longest" mode — pad shorter inputs with this value to the longest input's length. When omitted, the default truncate behavior applies.

Input​

Arrays—REQUIRED

Two or more lists, each wired to its own slot on the unlimited arr input.

Output​

Result

List of N-tuples (each tuple a JSON array containing one element from each input list at that index).
