Working with Excel spreadsheet

Hello guys.
I have created node Excrl reader, then node column filter widget and it is connected to the node Python script. As far as I understand, the data was transferred and Python sees it. But unfortunately, I don’t know how to extract them for calculations and how to access them

Hi @Alex_025 and welcome to the KNIME forum!

Have a look at the “Templates” tab of the Python Script node’s dialog. There are minimal examples.
Additionally, you can find complete example workflows at knime/Python Script Space – 01_Getting_Started – KNIME Community Hub .
There is also documentation available at KNIME Python API — KNIME Python API documentation .

Happy coding,
nan
