Hello, I have this question. I created node Excel reader, then column filter widger, to select columns I want. As far as I understand, they should pass to the node Python script as an array. But I don’t know how I can assign this array to a variable, for example, to perform the necessary actions.
You can learn in the node by looking at the examples in ‘Templates’ tab.
Besides that, take a look in the following code as starting point
import knime.scripting.io as knio import pandas as pd # data in df = knio.input_tables.to_pandas() # things happen print(df) # output as pd.DataFrame knio.output_tables = knio.Table.from_pandas(df)
You can add more input and output ports if the case.
