This Node Is Deprecated — This node is kept for backwards-compatibility, but the usage in new workflows is no longer recommended. The documentation below might contain more information.
Allows executing a Python script in a local Python
environment. The environment has to be configured
under File → Preferences → KNIME → Python or via flow variable, as described in the
KNIME Python Integration Installation Guide.
This node supports Python 2 and 3.
It also allows to import Jupyter notebooks as Python modules via the
knime_jupyter module that is available in the node's Python workspace.

Flow Variables
Input Ports
- The input table. In the Python script it is available as pandas.DataFrame under the name input_table.
Output Ports
- The first output table, contained in the variable output_table_1 which needs to be defined by the user script and has to be of type pandas.DataFrame.
- The second output table, contained in the variable output_table_2 which needs to be defined by the user script and has to be of type pandas.DataFrame.
