Is there any way to obtain more than output table from a python node?

[Mary_lea]

Hello,

I have a python node that works.

I would like to obtain as output three tables, doing this

1. knio.output_tables[0] = knio.Table.from_pandas(final_results)
2. knio.output_tables[1] = knio.Table.from_pandas(results.loc[errors_on_rows])
3. knio.output_tables[2] = knio.Table.from_pandas(df_where_cols_are_0)
4. But the program gives me the errorKeyError: ‘Invalid port index 1, only 1 output_table is available’

for an only table as output works
Can you help me?
Thank you in advance.
Regards,
Mary

@Mary_lea you can add ports as well as remove them. A little plus should appear if you hover over the right side of the node.

@Mary_lea as I have mentioned. Your Python nodes have a data port (the small black triangle) configured but in the code there is no line that would create this data. Such an output would look like this assuming df is a pandas dataframe (you might want to check the links provided above) # bring the dataframe back to KNIME knio.output_tables[0] = knio.Table.from_pandas(df) If you do not want any output you can remove this port. Then you would have to take care about the output yourself. [image…
