Multiple script task instances

Parent Previous Next


The following workflow properties have been set for the sequential script task:

The "Prepare Data" script task provides the collection and also initializes the result variable for the "Calculate Product" script task.

The workflow expression of the preparation task consists of this Python code:

Data = [1, 2, 3, 4]

Product = 1

So we have an array "Data" with the numbers we want to calculate the product with.

The workflow expression of the "Calculate Product" script task performs the actual calculation. This is done with the following Python code:

Product = Product * Token.Attributes["Figure"]

Result = Product

We obtain a value of the collection by addressing its element variable with Token.Attributes, calculate the product of the collection and store it in the result variable.
