The following are the step's expected inputs and outputs and their specific types.

Step signature

extract_node_pagerank(
    targets: list[number],
    *weights: list[number], 
    {
        "param": value
    }
) -> (pagerank: number)

where the object {"param": value} is optional in most cases and if present may contain any of the parameters described in the corresponding section below.

Example

Example call (in recipe editor)
