python script

Is there an alternative solution with any other nodes for if then else condition to manipulate the value of more than 1 column.

Hi @praskavi,

that seems to be a Python issue, what does the console or log say? Maybe stackoverflow can help?

But I suggest the non-legacy version of the Python integration anyway, have a look: KNIME Python Integration – KNIME Community Hub

Best regards

Hi,

did you try any of the suggestions?

For the rule engine node, please open a new forum thread with a clear example and in the best case with a minimal workflow to help your question.

I just saw you asked the same question in different topics, please don’t. I suggest to have a look at this thread.
